62139879 ÷ 807 
We're looking to find how many times 807 goes into 62139879.

Step 1:
If we divide 6 by 807, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 807

Moving on to step 2:
The number 807 fits into 62 0 times, leaving a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Append the next digit (1) from the dividend to 62 and continue with: 621 / 807

Advancing to step 3:
807 can be fit into 621 0 times, resulting in a remainder of 621.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 621 leaves us with 621.
Include the next digit (3) from the dividend after 621, then repeat: 6213 / 807

Going ahead to step 4:
807 goes into 6213 7 times with a remainder of 564.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 5649 from 6213 and we're left with 564.
Append the next digit (9) from the dividend to 564 and continue with: 5649 / 807

Advancing to step 5:
807 goes into 5649 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
Subtracting 5649 from 5649 leaves us with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 807

Advancing to step 6:
807 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 770.0
If we subtract 0 from 8, we get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 807

Step 7:
807 goes into 87 0 times with a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 7700.0
If we subtract 0 from 87, we get 87.
Append the next digit (9) from the dividend to 87 and continue with: 879 / 807

Step 8:
When dividing 879 by 807, we get 1 with a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 77001.0
The remainder is 72 after subtracting 807 from 879.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 9:
The number 807 fits into 720 0 times, leaving a remainder of 720.
Put 0 as the next digit of the answer. 
Result so far: 77001.0
If we take 0 away from 720, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Going ahead to step 10:
807 can be fit into 7200 8 times, resulting in a remainder of 744.
Use 8 as the next digit of our solution. 
Result so far: 77001.08
If we take 6456 away from 7200, we end up with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Advancing to step 11:
807 goes into 7440 9 times with a remainder of 177.
Record the quotient 9 as the next digit in the result. 
Result so far: 77001.089
Subtracting 7263 from 7440 leaves us with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Advancing to step 12:
When dividing 1770 by 807, we get 2 with a remainder of 156.
Write down 2 as next digit of the result. 
Result so far: 77001.0892
If we subtract 1614 from 1770, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 13:
When dividing 1560 by 807, we get 1 with a remainder of 753.
The next digit of our result is 1. 
Result so far: 77001.08921
If we subtract 807 from 1560, we get 753.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7530, and continue the process.

Step 14:
If we divide 7530 by 807, we get 9 and a remainder of 267.
The number 9 becomes the next digit in our result. 
Result so far: 77001.089219
If we take 7263 away from 7530, we end up with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

On to step 15:
When dividing 2670 by 807, we get 3 with a remainder of 249.
Put 3 as the next digit of the answer. 
Result so far: 77001.0892193
Deduct 2421 from 2670 and we're left with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Let's proceed to step 16:
The number 807 fits into 2490 3 times, leaving a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 77001.08921933
If we take 2421 away from 2490, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Our division results in 77001.08921933 with a remaining 6.9e-08.
