We're dividing 52071721 by 987 
We want to divide 52071721 by 987.

Step 1:
987 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
Deduct 0 from 5 and we're left with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 987

Moving on to step 2:
The number 987 fits into 52 0 times, leaving a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Take the next digit (0) from the dividend and append it to 52, then repeat: 520 / 987

Let's proceed to step 3:
If we divide 520 by 987, we get 0 and a remainder of 520.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 520, we get 520.
Fetch the next digit (7) from the dividend, attach it to 520 and continue: 5207 / 987

Moving on to step 4:
If we divide 5207 by 987, we get 5 and a remainder of 272.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 4935 from 5207 to get 272.
Include the next digit (1) from the dividend after 272, then repeat: 2721 / 987

Moving on to step 5:
If we divide 2721 by 987, we get 2 and a remainder of 747.
The next digit of our result is 2. 
Result so far: 52.0
If we take 1974 away from 2721, we end up with 747.
Append the next digit (7) from the dividend to 747 and continue with: 7477 / 987

Moving on to step 6:
When dividing 7477 by 987, we get 7 with a remainder of 568.
The next digit of our result is 7. 
Result so far: 527.0
Subtracting 6909 from 7477 leaves us with 568.
Fetch the next digit (2) from the dividend, attach it to 568 and continue: 5682 / 987

Moving on to step 7:
987 goes into 5682 5 times with a remainder of 747.
Put 5 as the next digit of the answer. 
Result so far: 5275.0
Subtracting 4935 from 5682 leaves us with 747.
Grab the next digit (1) from the dividend, add it to 747, then carry on: 7471 / 987

Advancing to step 8:
The number 987 fits into 7471 7 times, leaving a remainder of 562.
The number 7 becomes the next digit in our result. 
Result so far: 52757.0
Subtracting 6909 from 7471 leaves us with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Let's proceed to step 9:
When dividing 5620 by 987, we get 5 with a remainder of 685.
Use 5 as the next digit of our solution. 
Result so far: 52757.5
Subtracting 4935 from 5620 leaves us with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

On to step 10:
6850 divided by 987 is 6 with a remainder of 928.
The next digit of our result is 6. 
Result so far: 52757.56
Deduct 5922 from 6850 and we're left with 928.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9280, and continue the process.

Moving on to step 11:
987 can be fit into 9280 9 times, resulting in a remainder of 397.
Record the quotient 9 as the next digit in the result. 
Result so far: 52757.569
Subtract 8883 from 9280 to get 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Advancing to step 12:
When dividing 3970 by 987, we get 4 with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 52757.5694
The remainder is 22 after subtracting 3948 from 3970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
220 divided by 987 is 0 with a remainder of 220.
The next digit of our result is 0. 
Result so far: 52757.5694
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 14:
The number 987 fits into 2200 2 times, leaving a remainder of 226.
Put 2 as the next digit of the answer. 
Result so far: 52757.569402
Deduct 1974 from 2200 and we're left with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

On to step 15:
987 can be fit into 2260 2 times, resulting in a remainder of 286.
Write down 2 as next digit of the result. 
Result so far: 52757.5694022
The remainder is 286 after subtracting 1974 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

In conclusion, the division gives 52757.5694022 with a balance of 2.86e-06.
