72139233 ÷ 807 
We want to divide 72139233 by 807.

Step 1:
When dividing 7 by 807, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 807

Going ahead to step 2:
If we divide 72 by 807, we get 0 and a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Fetch the next digit (1) from the dividend, attach it to 72 and continue: 721 / 807

Moving on to step 3:
If we divide 721 by 807, we get 0 and a remainder of 721.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 721, we get 721.
Include the next digit (3) from the dividend after 721, then repeat: 7213 / 807

On to step 4:
807 can be fit into 7213 8 times, resulting in a remainder of 757.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 6456 from 7213 and we're left with 757.
Fetch the next digit (9) from the dividend, attach it to 757 and continue: 7579 / 807

On to step 5:
7579 divided by 807 is 9 with a remainder of 316.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
If we subtract 7263 from 7579, we get 316.
Fetch the next digit (2) from the dividend, attach it to 316 and continue: 3162 / 807

Going ahead to step 6:
If we divide 3162 by 807, we get 3 and a remainder of 741.
Write down 3 as next digit of the result. 
Result so far: 893.0
Deduct 2421 from 3162 and we're left with 741.
Append the next digit (3) from the dividend to 741 and continue with: 7413 / 807

Advancing to step 7:
The number 807 fits into 7413 9 times, leaving a remainder of 150.
The number 9 becomes the next digit in our result. 
Result so far: 8939.0
The remainder is 150 after subtracting 7263 from 7413.
Include the next digit (3) from the dividend after 150, then repeat: 1503 / 807

Step 8:
807 can be fit into 1503 1 times, resulting in a remainder of 696.
Write down 1 as next digit of the result. 
Result so far: 89391.0
If we subtract 807 from 1503, we get 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

On to step 9:
When dividing 6960 by 807, we get 8 with a remainder of 504.
The next digit of our result is 8. 
Result so far: 89391.8
Subtract 6456 from 6960 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Going ahead to step 10:
5040 divided by 807 is 6 with a remainder of 198.
The number 6 becomes the next digit in our result. 
Result so far: 89391.86
Subtract 4842 from 5040 to get 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 11:
If we divide 1980 by 807, we get 2 and a remainder of 366.
Write down 2 as next digit of the result. 
Result so far: 89391.862
Deduct 1614 from 1980 and we're left with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 12:
If we divide 3660 by 807, we get 4 and a remainder of 432.
Use 4 as the next digit of our solution. 
Result so far: 89391.8624
If we take 3228 away from 3660, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 13:
If we divide 4320 by 807, we get 5 and a remainder of 285.
Use 5 as the next digit of our solution. 
Result so far: 89391.86245
The remainder is 285 after subtracting 4035 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 14:
807 can be fit into 2850 3 times, resulting in a remainder of 429.
Write down 3 as next digit of the result. 
Result so far: 89391.862453
If we subtract 2421 from 2850, we get 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Moving on to step 15:
807 goes into 4290 5 times with a remainder of 255.
Record the quotient 5 as the next digit in the result. 
Result so far: 89391.8624535
Subtracting 4035 from 4290 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 16:
807 goes into 2550 3 times with a remainder of 129.
Write down 3 as next digit of the result. 
Result so far: 89391.86245353
Subtract 2421 from 2550 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

The quotient of the division is 89391.86245353, and the remainder is 1.29e-07.
