We look at the division of 53455963 by 921 
We're looking to find how many times 921 goes into 53455963.

On to step 1:
921 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 921

Going ahead to step 2:
The number 921 fits into 53 0 times, leaving a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Bring next digit (4) of the dividend behind the 53 and repeat the process: 534 / 921

On to step 3:
When dividing 534 by 921, we get 0 with a remainder of 534.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 534 to get 534.
Grab the next digit (5) from the dividend, add it to 534, then carry on: 5345 / 921

On to step 4:
921 can be fit into 5345 5 times, resulting in a remainder of 740.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 4605 from 5345, we get 740.
Take the next digit (5) from the dividend and append it to 740, then repeat: 7405 / 921

Advancing to step 5:
When dividing 7405 by 921, we get 8 with a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 58.0
The remainder is 37 after subtracting 7368 from 7405.
Fetch the next digit (9) from the dividend, attach it to 37 and continue: 379 / 921

Going ahead to step 6:
The number 921 fits into 379 0 times, leaving a remainder of 379.
Put 0 as the next digit of the answer. 
Result so far: 580.0
Subtracting 0 from 379 leaves us with 379.
Take the next digit (6) from the dividend and append it to 379, then repeat: 3796 / 921

Step 7:
3796 divided by 921 is 4 with a remainder of 112.
Put 4 as the next digit of the answer. 
Result so far: 5804.0
If we take 3684 away from 3796, we end up with 112.
Fetch the next digit (3) from the dividend, attach it to 112 and continue: 1123 / 921

Going ahead to step 8:
921 goes into 1123 1 times with a remainder of 202.
Record the quotient 1 as the next digit in the result. 
Result so far: 58041.0
The remainder is 202 after subtracting 921 from 1123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 9:
When dividing 2020 by 921, we get 2 with a remainder of 178.
Record the quotient 2 as the next digit in the result. 
Result so far: 58041.2
The remainder is 178 after subtracting 1842 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Let's proceed to step 10:
1780 divided by 921 is 1 with a remainder of 859.
Put 1 as the next digit of the answer. 
Result so far: 58041.21
If we take 921 away from 1780, we end up with 859.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8590, and continue the process.

On to step 11:
921 goes into 8590 9 times with a remainder of 301.
Use 9 as the next digit of our solution. 
Result so far: 58041.219
Deduct 8289 from 8590 and we're left with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Advancing to step 12:
921 can be fit into 3010 3 times, resulting in a remainder of 247.
The next digit of our result is 3. 
Result so far: 58041.2193
If we take 2763 away from 3010, we end up with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Advancing to step 13:
2470 divided by 921 is 2 with a remainder of 628.
Write down 2 as next digit of the result. 
Result so far: 58041.21932
If we take 1842 away from 2470, we end up with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Moving on to step 14:
The number 921 fits into 6280 6 times, leaving a remainder of 754.
The next digit of our result is 6. 
Result so far: 58041.219326
If we subtract 5526 from 6280, we get 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Let's proceed to step 15:
The number 921 fits into 7540 8 times, leaving a remainder of 172.
The number 8 becomes the next digit in our result. 
Result so far: 58041.2193268
If we take 7368 away from 7540, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 16:
921 goes into 1720 1 times with a remainder of 799.
Put 1 as the next digit of the answer. 
Result so far: 58041.21932681
If we subtract 921 from 1720, we get 799.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7990, and continue the process.

In conclusion, the division gives 58041.21932681 with a balance of 7.99e-07.
