We're dividing 72369783 by 86 
Let's see how many times 86 fits into 72369783.

Advancing to step 1:
When dividing 7 by 86, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 86

Let's proceed to step 2:
The number 86 fits into 72 0 times, leaving a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Include the next digit (3) from the dividend after 72, then repeat: 723 / 86

Going ahead to step 3:
When dividing 723 by 86, we get 8 with a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 688 from 723 leaves us with 35.
Append the next digit (6) from the dividend to 35 and continue with: 356 / 86

Going ahead to step 4:
The number 86 fits into 356 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Subtract 344 from 356 to get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 86

On to step 5:
When dividing 129 by 86, we get 1 with a remainder of 43.
The next digit of our result is 1. 
Result so far: 841.0
Deduct 86 from 129 and we're left with 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 86

Let's proceed to step 6:
437 divided by 86 is 5 with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 8415.0
Subtracting 430 from 437 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 86

On to step 7:
If we divide 78 by 86, we get 0 and a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 84150.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (3) from the dividend, attach it to 78 and continue: 783 / 86

Let's proceed to step 8:
When dividing 783 by 86, we get 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 841509.0
If we take 774 away from 783, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
86 goes into 90 1 times with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 841509.1
The remainder is 4 after subtracting 86 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
The number 86 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 841509.1
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
86 goes into 400 4 times with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 841509.104
Subtracting 344 from 400 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 12:
560 divided by 86 is 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 841509.1046
If we take 516 away from 560, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
86 goes into 440 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 841509.10465
Subtract 430 from 440 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
If we divide 100 by 86, we get 1 and a remainder of 14.
The next digit of our result is 1. 
Result so far: 841509.104651
If we take 86 away from 100, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 15:
140 divided by 86 is 1 with a remainder of 54.
The next digit of our result is 1. 
Result so far: 841509.1046511
Deduct 86 from 140 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 841509.1046511, and the remainder is 5.4e-07.
