We're dividing 13442679 by 858 
We want to figure out the number of times 13442679 can be divided by 858.

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
If we take 0 away from 1, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 858

Step 2:
When dividing 13 by 858, we get 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 858

Advancing to step 3:
858 can be fit into 134 0 times, resulting in a remainder of 134.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 134 to get 134.
Take the next digit (4) from the dividend and append it to 134, then repeat: 1344 / 858

Moving on to step 4:
858 can be fit into 1344 1 times, resulting in a remainder of 486.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 858 from 1344, we get 486.
Grab the next digit (2) from the dividend, add it to 486, then carry on: 4862 / 858

Going ahead to step 5:
When dividing 4862 by 858, we get 5 with a remainder of 572.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 4290 from 4862 to get 572.
Include the next digit (6) from the dividend after 572, then repeat: 5726 / 858

On to step 6:
858 can be fit into 5726 6 times, resulting in a remainder of 578.
Use 6 as the next digit of our solution. 
Result so far: 156.0
Subtracting 5148 from 5726 leaves us with 578.
Fetch the next digit (7) from the dividend, attach it to 578 and continue: 5787 / 858

On to step 7:
858 goes into 5787 6 times with a remainder of 639.
Use 6 as the next digit of our solution. 
Result so far: 1566.0
Subtracting 5148 from 5787 leaves us with 639.
Include the next digit (9) from the dividend after 639, then repeat: 6399 / 858

Advancing to step 8:
If we divide 6399 by 858, we get 7 and a remainder of 393.
The next digit of our result is 7. 
Result so far: 15667.0
Deduct 6006 from 6399 and we're left with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Let's proceed to step 9:
858 goes into 3930 4 times with a remainder of 498.
Use 4 as the next digit of our solution. 
Result so far: 15667.4
If we subtract 3432 from 3930, we get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Step 10:
858 can be fit into 4980 5 times, resulting in a remainder of 690.
The number 5 becomes the next digit in our result. 
Result so far: 15667.45
The remainder is 690 after subtracting 4290 from 4980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Going ahead to step 11:
When dividing 6900 by 858, we get 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 15667.458
Subtracting 6864 from 6900 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
858 can be fit into 360 0 times, resulting in a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 15667.458
Subtracting 0 from 360 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 13:
The number 858 fits into 3600 4 times, leaving a remainder of 168.
Put 4 as the next digit of the answer. 
Result so far: 15667.45804
The remainder is 168 after subtracting 3432 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 14:
When dividing 1680 by 858, we get 1 with a remainder of 822.
The number 1 becomes the next digit in our result. 
Result so far: 15667.458041
Subtracting 858 from 1680 leaves us with 822.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

On to step 15:
8220 divided by 858 is 9 with a remainder of 498.
Write down 9 as next digit of the result. 
Result so far: 15667.4580419
Subtract 7722 from 8220 to get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Step 16:
4980 divided by 858 is 5 with a remainder of 690.
The next digit of our result is 5. 
Result so far: 15667.45804195
Deduct 4290 from 4980 and we're left with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

The quotient of the division is 15667.45804195, and the remainder is 6.9e-07.
