Let's divide 51528120 by 921
Let's see how many times 921 fits into 51528120.

On to step 1:
5 divided by 921 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 921

On to step 2:
The number 921 fits into 51 0 times, leaving a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 921

On to step 3:
515 divided by 921 is 0 with a remainder of 515.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 515, we get 515.
Fetch the next digit (2) from the dividend, attach it to 515 and continue: 5152 / 921

Step 4:
921 goes into 5152 5 times with a remainder of 547.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 4605 from 5152 and we're left with 547.
Include the next digit (8) from the dividend after 547, then repeat: 5478 / 921

Moving on to step 5:
5478 divided by 921 is 5 with a remainder of 873.
The next digit of our result is 5. 
Result so far: 55.0
Subtracting 4605 from 5478 leaves us with 873.
Append the next digit (1) from the dividend to 873 and continue with: 8731 / 921

Going ahead to step 6:
921 goes into 8731 9 times with a remainder of 442.
Put 9 as the next digit of the answer. 
Result so far: 559.0
Subtracting 8289 from 8731 leaves us with 442.
Fetch the next digit (2) from the dividend, attach it to 442 and continue: 4422 / 921

Moving on to step 7:
921 goes into 4422 4 times with a remainder of 738.
Record the quotient 4 as the next digit in the result. 
Result so far: 5594.0
The remainder is 738 after subtracting 3684 from 4422.
Grab the next digit (0) from the dividend, add it to 738, then carry on: 7380 / 921

Going ahead to step 8:
The number 921 fits into 7380 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 55948.0
Subtracting 7368 from 7380 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
921 goes into 120 0 times with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 55948.0
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 10:
If we divide 1200 by 921, we get 1 and a remainder of 279.
The next digit of our result is 1. 
Result so far: 55948.01
If we subtract 921 from 1200, we get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Moving on to step 11:
When dividing 2790 by 921, we get 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 55948.013
Subtracting 2763 from 2790 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 12:
921 goes into 270 0 times with a remainder of 270.
Put 0 as the next digit of the answer. 
Result so far: 55948.013
If we subtract 0 from 270, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 13:
921 can be fit into 2700 2 times, resulting in a remainder of 858.
The next digit of our result is 2. 
Result so far: 55948.01302
If we take 1842 away from 2700, we end up with 858.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8580, and continue the process.

Step 14:
When dividing 8580 by 921, we get 9 with a remainder of 291.
The next digit of our result is 9. 
Result so far: 55948.013029
The remainder is 291 after subtracting 8289 from 8580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Let's proceed to step 15:
2910 divided by 921 is 3 with a remainder of 147.
Write down 3 as next digit of the result. 
Result so far: 55948.0130293
Subtracting 2763 from 2910 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Step 16:
1470 divided by 921 is 1 with a remainder of 549.
Record the quotient 1 as the next digit in the result. 
Result so far: 55948.01302931
Deduct 921 from 1470 and we're left with 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

In conclusion, the division gives 55948.01302931 with a balance of 5.49e-07.
