We divide 15189372 by 858
We want to divide 15189372 by 858.

Let's proceed to step 1:
The number 858 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 858

On to step 2:
When dividing 15 by 858, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 858

On to step 3:
If we divide 151 by 858, we get 0 and a remainder of 151.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 151, we end up with 151.
Take the next digit (8) from the dividend and append it to 151, then repeat: 1518 / 858

Let's proceed to step 4:
The number 858 fits into 1518 1 times, leaving a remainder of 660.
The next digit of our result is 1. 
Result so far: 1.0
If we take 858 away from 1518, we end up with 660.
Include the next digit (9) from the dividend after 660, then repeat: 6609 / 858

On to step 5:
When dividing 6609 by 858, we get 7 with a remainder of 603.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtracting 6006 from 6609 leaves us with 603.
Bring next digit (3) of the dividend behind the 603 and repeat the process: 6033 / 858

Step 6:
When dividing 6033 by 858, we get 7 with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 177.0
Deduct 6006 from 6033 and we're left with 27.
Bring next digit (7) of the dividend behind the 27 and repeat the process: 277 / 858

Let's proceed to step 7:
The number 858 fits into 277 0 times, leaving a remainder of 277.
Use 0 as the next digit of our solution. 
Result so far: 1770.0
Subtract 0 from 277 to get 277.
Fetch the next digit (2) from the dividend, attach it to 277 and continue: 2772 / 858

Step 8:
The number 858 fits into 2772 3 times, leaving a remainder of 198.
The next digit of our result is 3. 
Result so far: 17703.0
If we take 2574 away from 2772, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 9:
858 goes into 1980 2 times with a remainder of 264.
The next digit of our result is 2. 
Result so far: 17703.2
If we subtract 1716 from 1980, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 10:
If we divide 2640 by 858, we get 3 and a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 17703.23
The remainder is 66 after subtracting 2574 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 11:
If we divide 660 by 858, we get 0 and a remainder of 660.
The number 0 becomes the next digit in our result. 
Result so far: 17703.23
Deduct 0 from 660 and we're left with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 12:
When dividing 6600 by 858, we get 7 with a remainder of 594.
Record the quotient 7 as the next digit in the result. 
Result so far: 17703.2307
Subtracting 6006 from 6600 leaves us with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Advancing to step 13:
The number 858 fits into 5940 6 times, leaving a remainder of 792.
Record the quotient 6 as the next digit in the result. 
Result so far: 17703.23076
Deduct 5148 from 5940 and we're left with 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Advancing to step 14:
The number 858 fits into 7920 9 times, leaving a remainder of 198.
Put 9 as the next digit of the answer. 
Result so far: 17703.230769
If we take 7722 away from 7920, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 15:
The number 858 fits into 1980 2 times, leaving a remainder of 264.
The number 2 becomes the next digit in our result. 
Result so far: 17703.2307692
Subtracting 1716 from 1980 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 16:
The number 858 fits into 2640 3 times, leaving a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 17703.23076923
If we take 2574 away from 2640, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

After the division, we end up with 17703.23076923 and a remainder of 6.6e-08.
