We're dividing 18615536 by 858 
We're looking to find how many times 858 goes into 18615536.

Let's proceed to step 1:
If we divide 1 by 858, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 858

Advancing to step 2:
The number 858 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 858

Moving on to step 3:
858 goes into 186 0 times with a remainder of 186.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 186 to get 186.
Append the next digit (1) from the dividend to 186 and continue with: 1861 / 858

Moving on to step 4:
1861 divided by 858 is 2 with a remainder of 145.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1716 away from 1861, we end up with 145.
Take the next digit (5) from the dividend and append it to 145, then repeat: 1455 / 858

Step 5:
When dividing 1455 by 858, we get 1 with a remainder of 597.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 858 away from 1455, we end up with 597.
Grab the next digit (5) from the dividend, add it to 597, then carry on: 5975 / 858

Going ahead to step 6:
The number 858 fits into 5975 6 times, leaving a remainder of 827.
The number 6 becomes the next digit in our result. 
Result so far: 216.0
Subtracting 5148 from 5975 leaves us with 827.
Take the next digit (3) from the dividend and append it to 827, then repeat: 8273 / 858

Let's proceed to step 7:
When dividing 8273 by 858, we get 9 with a remainder of 551.
The next digit of our result is 9. 
Result so far: 2169.0
The remainder is 551 after subtracting 7722 from 8273.
Append the next digit (6) from the dividend to 551 and continue with: 5516 / 858

Step 8:
5516 divided by 858 is 6 with a remainder of 368.
Write down 6 as next digit of the result. 
Result so far: 21696.0
Subtract 5148 from 5516 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 9:
3680 divided by 858 is 4 with a remainder of 248.
Use 4 as the next digit of our solution. 
Result so far: 21696.4
Subtract 3432 from 3680 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 10:
The number 858 fits into 2480 2 times, leaving a remainder of 764.
Use 2 as the next digit of our solution. 
Result so far: 21696.42
Deduct 1716 from 2480 and we're left with 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Let's proceed to step 11:
When dividing 7640 by 858, we get 8 with a remainder of 776.
The number 8 becomes the next digit in our result. 
Result so far: 21696.428
If we subtract 6864 from 7640, we get 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Let's proceed to step 12:
858 goes into 7760 9 times with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 21696.4289
If we subtract 7722 from 7760, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
When dividing 380 by 858, we get 0 with a remainder of 380.
The next digit of our result is 0. 
Result so far: 21696.4289
The remainder is 380 after subtracting 0 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 14:
If we divide 3800 by 858, we get 4 and a remainder of 368.
Put 4 as the next digit of the answer. 
Result so far: 21696.428904
Subtracting 3432 from 3800 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 15:
3680 divided by 858 is 4 with a remainder of 248.
Record the quotient 4 as the next digit in the result. 
Result so far: 21696.4289044
If we subtract 3432 from 3680, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Our division results in 21696.4289044 with a remaining 2.48e-06.
