Let's divide 83389997 by 72
We're looking to find how many times 72 goes into 83389997.

Going ahead to step 1:
When dividing 8 by 72, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 72

Moving on to step 2:
72 can be fit into 83 1 times, resulting in a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 11 after subtracting 72 from 83.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 72

Going ahead to step 3:
72 can be fit into 113 1 times, resulting in a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 72 away from 113, we end up with 41.
Append the next digit (8) from the dividend to 41 and continue with: 418 / 72

Going ahead to step 4:
If we divide 418 by 72, we get 5 and a remainder of 58.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
If we subtract 360 from 418, we get 58.
Grab the next digit (9) from the dividend, add it to 58, then carry on: 589 / 72

Let's proceed to step 5:
If we divide 589 by 72, we get 8 and a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 1158.0
The remainder is 13 after subtracting 576 from 589.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 72

Let's proceed to step 6:
72 can be fit into 139 1 times, resulting in a remainder of 67.
The next digit of our result is 1. 
Result so far: 11581.0
Subtracting 72 from 139 leaves us with 67.
Bring next digit (9) of the dividend behind the 67 and repeat the process: 679 / 72

Advancing to step 7:
When dividing 679 by 72, we get 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 115819.0
Deduct 648 from 679 and we're left with 31.
Grab the next digit (7) from the dividend, add it to 31, then carry on: 317 / 72

On to step 8:
72 goes into 317 4 times with a remainder of 29.
Record the quotient 4 as the next digit in the result. 
Result so far: 1158194.0
The remainder is 29 after subtracting 288 from 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 9:
72 goes into 290 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 1158194.4
If we take 288 away from 290, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
72 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1158194.4
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
72 can be fit into 200 2 times, resulting in a remainder of 56.
The next digit of our result is 2. 
Result so far: 1158194.402
The remainder is 56 after subtracting 144 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
72 can be fit into 560 7 times, resulting in a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 1158194.4027
Subtracting 504 from 560 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.

Advancing to step 13:
72 goes into 560 7 times with a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 1158194.40277
Subtract 504 from 560 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 1158194.40277, with a leftover of 5.6e-05.
