51820691 ÷ 997 
Our goal is to divide 51820691 by 997.

On to step 1:
If we divide 5 by 997, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 997

Step 2:
997 can be fit into 51 0 times, resulting in a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 997

On to step 3:
518 divided by 997 is 0 with a remainder of 518.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 518 and we're left with 518.
Take the next digit (2) from the dividend and append it to 518, then repeat: 5182 / 997

Moving on to step 4:
997 goes into 5182 5 times with a remainder of 197.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 4985 from 5182, we get 197.
Take the next digit (0) from the dividend and append it to 197, then repeat: 1970 / 997

Let's proceed to step 5:
997 goes into 1970 1 times with a remainder of 973.
Use 1 as the next digit of our solution. 
Result so far: 51.0
Deduct 997 from 1970 and we're left with 973.
Fetch the next digit (6) from the dividend, attach it to 973 and continue: 9736 / 997

Going ahead to step 6:
997 can be fit into 9736 9 times, resulting in a remainder of 763.
Record the quotient 9 as the next digit in the result. 
Result so far: 519.0
Subtracting 8973 from 9736 leaves us with 763.
Bring next digit (9) of the dividend behind the 763 and repeat the process: 7639 / 997

Moving on to step 7:
7639 divided by 997 is 7 with a remainder of 660.
Write down 7 as next digit of the result. 
Result so far: 5197.0
Subtracting 6979 from 7639 leaves us with 660.
Grab the next digit (1) from the dividend, add it to 660, then carry on: 6601 / 997

Advancing to step 8:
When dividing 6601 by 997, we get 6 with a remainder of 619.
Use 6 as the next digit of our solution. 
Result so far: 51976.0
The remainder is 619 after subtracting 5982 from 6601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Going ahead to step 9:
997 goes into 6190 6 times with a remainder of 208.
Put 6 as the next digit of the answer. 
Result so far: 51976.6
If we subtract 5982 from 6190, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 10:
The number 997 fits into 2080 2 times, leaving a remainder of 86.
The number 2 becomes the next digit in our result. 
Result so far: 51976.62
Deduct 1994 from 2080 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 11:
If we divide 860 by 997, we get 0 and a remainder of 860.
The next digit of our result is 0. 
Result so far: 51976.62
The remainder is 860 after subtracting 0 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Moving on to step 12:
997 can be fit into 8600 8 times, resulting in a remainder of 624.
The next digit of our result is 8. 
Result so far: 51976.6208
Subtract 7976 from 8600 to get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Step 13:
997 can be fit into 6240 6 times, resulting in a remainder of 258.
Write down 6 as next digit of the result. 
Result so far: 51976.62086
Subtracting 5982 from 6240 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Step 14:
2580 divided by 997 is 2 with a remainder of 586.
Put 2 as the next digit of the answer. 
Result so far: 51976.620862
Deduct 1994 from 2580 and we're left with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Going ahead to step 15:
997 goes into 5860 5 times with a remainder of 875.
Put 5 as the next digit of the answer. 
Result so far: 51976.6208625
The remainder is 875 after subtracting 4985 from 5860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8750, and continue the process.

On to step 16:
If we divide 8750 by 997, we get 8 and a remainder of 774.
The number 8 becomes the next digit in our result. 
Result so far: 51976.62086258
The remainder is 774 after subtracting 7976 from 8750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

Our division results in 51976.62086258 with a remaining 7.74e-07.
