We're dividing 61639614 by 72 
We're looking to find how many times 72 goes into 61639614.

Advancing to step 1:
When dividing 6 by 72, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 72

Going ahead to step 2:
72 goes into 61 0 times with a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Append the next digit (6) from the dividend to 61 and continue with: 616 / 72

Step 3:
If we divide 616 by 72, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 576 from 616, we get 40.
Take the next digit (3) from the dividend and append it to 40, then repeat: 403 / 72

Moving on to step 4:
403 divided by 72 is 5 with a remainder of 43.
The next digit of our result is 5. 
Result so far: 85.0
Subtracting 360 from 403 leaves us with 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 72

On to step 5:
439 divided by 72 is 6 with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 856.0
Deduct 432 from 439 and we're left with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 72

On to step 6:
When dividing 76 by 72, we get 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 8561.0
The remainder is 4 after subtracting 72 from 76.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 72

Step 7:
72 goes into 41 0 times with a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 85610.0
Deduct 0 from 41 and we're left with 41.
Take the next digit (4) from the dividend and append it to 41, then repeat: 414 / 72

Going ahead to step 8:
The number 72 fits into 414 5 times, leaving a remainder of 54.
The next digit of our result is 5. 
Result so far: 856105.0
Deduct 360 from 414 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.

Step 9:
540 divided by 72 is 7 with a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 856105.7
Subtract 504 from 540 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
When dividing 360 by 72, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 856105.75
Subtract 360 from 360 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
72 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 856105.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
0 divided by 72 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 856105.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 856105.75 with a remaining 0.0.
