Let's divide 61978020 by 72
We want to figure out the number of times 61978020 can be divided by 72.

Moving on to step 1:
72 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 72

On 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
If we take 0 away from 61, we end up with 61.
Grab the next digit (9) from the dividend, add it to 61, then carry on: 619 / 72

Advancing to step 3:
If we divide 619 by 72, we get 8 and a remainder of 43.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 576 from 619 and we're left with 43.
Append the next digit (7) from the dividend to 43 and continue with: 437 / 72

On to step 4:
The number 72 fits into 437 6 times, leaving a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtracting 432 from 437 leaves us with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 72

Step 5:
If we divide 58 by 72, we get 0 and a remainder of 58.
The next digit of our result is 0. 
Result so far: 860.0
If we take 0 away from 58, we end up with 58.
Include the next digit (0) from the dividend after 58, then repeat: 580 / 72

Let's proceed to step 6:
580 divided by 72 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 8608.0
If we subtract 576 from 580, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 72

Advancing to step 7:
72 goes into 42 0 times with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 86080.0
If we subtract 0 from 42, we get 42.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 72

On to step 8:
If we divide 420 by 72, we get 5 and a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 860805.0
The remainder is 60 after subtracting 360 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
If we divide 600 by 72, we get 8 and a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 860805.8
The remainder is 24 after subtracting 576 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
When dividing 240 by 72, we get 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 860805.83
Subtracting 216 from 240 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
72 goes into 240 3 times with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 860805.833
If we take 216 away from 240, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 860805.833 with a balance of 0.0024.
