Let's divide 72172408 by 71
We want to divide 72172408 by 71.

Advancing to step 1:
When dividing 7 by 71, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 71

Step 2:
72 divided by 71 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 71 from 72 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 71

On to step 3:
11 divided by 71 is 0 with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 11 and we're left with 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 71

Let's proceed to step 4:
117 divided by 71 is 1 with a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Subtract 71 from 117 to get 46.
Grab the next digit (2) from the dividend, add it to 46, then carry on: 462 / 71

Moving on to step 5:
462 divided by 71 is 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 1016.0
Deduct 426 from 462 and we're left with 36.
Bring next digit (4) of the dividend behind the 36 and repeat the process: 364 / 71

Going ahead to step 6:
The number 71 fits into 364 5 times, leaving a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 10165.0
Deduct 355 from 364 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 71

On to step 7:
The number 71 fits into 90 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 101651.0
Subtracting 71 from 90 leaves us with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 71

Advancing to step 8:
The number 71 fits into 198 2 times, leaving a remainder of 56.
The next digit of our result is 2. 
Result so far: 1016512.0
If we subtract 142 from 198, we 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.

Let's proceed to step 9:
71 goes into 560 7 times with a remainder of 63.
The next digit of our result is 7. 
Result so far: 1016512.7
If we subtract 497 from 560, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 10:
630 divided by 71 is 8 with a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 1016512.78
The remainder is 62 after subtracting 568 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 11:
71 goes into 620 8 times with a remainder of 52.
The next digit of our result is 8. 
Result so far: 1016512.788
If we take 568 away from 620, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 1016512.788 and a remainder of 0.0052.
