We divide 72186728 by 83
We want to divide 72186728 by 83.

Advancing to step 1:
83 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 83

On to step 2:
83 can be fit into 72 0 times, resulting in a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Fetch the next digit (1) from the dividend, attach it to 72 and continue: 721 / 83

On to step 3:
83 goes into 721 8 times with a remainder of 57.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 664 from 721 leaves us with 57.
Append the next digit (8) from the dividend to 57 and continue with: 578 / 83

Advancing to step 4:
The number 83 fits into 578 6 times, leaving a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
The remainder is 80 after subtracting 498 from 578.
Fetch the next digit (6) from the dividend, attach it to 80 and continue: 806 / 83

Step 5:
When dividing 806 by 83, we get 9 with a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 869.0
Subtract 747 from 806 to get 59.
Fetch the next digit (7) from the dividend, attach it to 59 and continue: 597 / 83

Moving on to step 6:
597 divided by 83 is 7 with a remainder of 16.
The next digit of our result is 7. 
Result so far: 8697.0
Deduct 581 from 597 and we're left with 16.
Take the next digit (2) from the dividend and append it to 16, then repeat: 162 / 83

Let's proceed to step 7:
The number 83 fits into 162 1 times, leaving a remainder of 79.
The number 1 becomes the next digit in our result. 
Result so far: 86971.0
If we take 83 away from 162, we end up with 79.
Bring next digit (8) of the dividend behind the 79 and repeat the process: 798 / 83

On to step 8:
The number 83 fits into 798 9 times, leaving a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 869719.0
Deduct 747 from 798 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 9:
83 goes into 510 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 869719.6
The remainder is 12 after subtracting 498 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
83 can be fit into 120 1 times, resulting in a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 869719.61
Subtracting 83 from 120 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 11:
83 can be fit into 370 4 times, resulting in a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 869719.614
Deduct 332 from 370 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 12:
380 divided by 83 is 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 869719.6144
Subtract 332 from 380 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 869719.6144, with a leftover of 0.00048.
