We look at the division of 51771996 by 722 
Let's see how many times 722 fits into 51771996.

On to step 1:
722 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 722

On to step 2:
722 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Grab the next digit (7) from the dividend, add it to 51, then carry on: 517 / 722

Moving on to step 3:
517 divided by 722 is 0 with a remainder of 517.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 517 and we're left with 517.
Append the next digit (7) from the dividend to 517 and continue with: 5177 / 722

On to step 4:
5177 divided by 722 is 7 with a remainder of 123.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 5054 away from 5177, we end up with 123.
Bring next digit (1) of the dividend behind the 123 and repeat the process: 1231 / 722

Going ahead to step 5:
The number 722 fits into 1231 1 times, leaving a remainder of 509.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
Deduct 722 from 1231 and we're left with 509.
Grab the next digit (9) from the dividend, add it to 509, then carry on: 5099 / 722

Step 6:
5099 divided by 722 is 7 with a remainder of 45.
The next digit of our result is 7. 
Result so far: 717.0
Subtracting 5054 from 5099 leaves us with 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 722

On to step 7:
459 divided by 722 is 0 with a remainder of 459.
Put 0 as the next digit of the answer. 
Result so far: 7170.0
The remainder is 459 after subtracting 0 from 459.
Take the next digit (6) from the dividend and append it to 459, then repeat: 4596 / 722

Going ahead to step 8:
722 can be fit into 4596 6 times, resulting in a remainder of 264.
Put 6 as the next digit of the answer. 
Result so far: 71706.0
If we take 4332 away from 4596, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 9:
722 goes into 2640 3 times with a remainder of 474.
Use 3 as the next digit of our solution. 
Result so far: 71706.3
Subtracting 2166 from 2640 leaves us with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Going ahead to step 10:
If we divide 4740 by 722, we get 6 and a remainder of 408.
Write down 6 as next digit of the result. 
Result so far: 71706.36
If we subtract 4332 from 4740, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 11:
If we divide 4080 by 722, we get 5 and a remainder of 470.
The number 5 becomes the next digit in our result. 
Result so far: 71706.365
Subtract 3610 from 4080 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 12:
If we divide 4700 by 722, we get 6 and a remainder of 368.
Record the quotient 6 as the next digit in the result. 
Result so far: 71706.3656
If we subtract 4332 from 4700, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 13:
3680 divided by 722 is 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 71706.36565
Subtract 3610 from 3680 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 14:
When dividing 700 by 722, we get 0 with a remainder of 700.
The number 0 becomes the next digit in our result. 
Result so far: 71706.36565
Subtract 0 from 700 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 15:
If we divide 7000 by 722, we get 9 and a remainder of 502.
The next digit of our result is 9. 
Result so far: 71706.3656509
Subtracting 6498 from 7000 leaves us with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Advancing to step 16:
722 can be fit into 5020 6 times, resulting in a remainder of 688.
The next digit of our result is 6. 
Result so far: 71706.36565096
If we subtract 4332 from 5020, we get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

After the division, we end up with 71706.36565096 and a remainder of 6.88e-07.
