We're dividing 51077112 by 921 
The aim is to understand the frequency of 921 in 51077112.

Advancing to step 1:
5 divided by 921 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 921

Step 2:
921 goes into 51 0 times with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 921

Advancing to step 3:
When dividing 510 by 921, we get 0 with a remainder of 510.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 510 after subtracting 0 from 510.
Bring next digit (7) of the dividend behind the 510 and repeat the process: 5107 / 921

Step 4:
If we divide 5107 by 921, we get 5 and a remainder of 502.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 4605 from 5107 and we're left with 502.
Fetch the next digit (7) from the dividend, attach it to 502 and continue: 5027 / 921

Step 5:
When dividing 5027 by 921, we get 5 with a remainder of 422.
Write down 5 as next digit of the result. 
Result so far: 55.0
Subtract 4605 from 5027 to get 422.
Grab the next digit (1) from the dividend, add it to 422, then carry on: 4221 / 921

Advancing to step 6:
The number 921 fits into 4221 4 times, leaving a remainder of 537.
Record the quotient 4 as the next digit in the result. 
Result so far: 554.0
The remainder is 537 after subtracting 3684 from 4221.
Bring next digit (1) of the dividend behind the 537 and repeat the process: 5371 / 921

On to step 7:
921 can be fit into 5371 5 times, resulting in a remainder of 766.
Use 5 as the next digit of our solution. 
Result so far: 5545.0
Deduct 4605 from 5371 and we're left with 766.
Take the next digit (2) from the dividend and append it to 766, then repeat: 7662 / 921

Advancing to step 8:
The number 921 fits into 7662 8 times, leaving a remainder of 294.
Write down 8 as next digit of the result. 
Result so far: 55458.0
Subtracting 7368 from 7662 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 9:
921 goes into 2940 3 times with a remainder of 177.
Put 3 as the next digit of the answer. 
Result so far: 55458.3
Subtract 2763 from 2940 to get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Going ahead to step 10:
The number 921 fits into 1770 1 times, leaving a remainder of 849.
The next digit of our result is 1. 
Result so far: 55458.31
Subtract 921 from 1770 to get 849.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8490, and continue the process.

Going ahead to step 11:
921 can be fit into 8490 9 times, resulting in a remainder of 201.
Write down 9 as next digit of the result. 
Result so far: 55458.319
The remainder is 201 after subtracting 8289 from 8490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Going ahead to step 12:
2010 divided by 921 is 2 with a remainder of 168.
Write down 2 as next digit of the result. 
Result so far: 55458.3192
If we subtract 1842 from 2010, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 13:
The number 921 fits into 1680 1 times, leaving a remainder of 759.
Write down 1 as next digit of the result. 
Result so far: 55458.31921
Subtract 921 from 1680 to get 759.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7590, and continue the process.

Moving on to step 14:
7590 divided by 921 is 8 with a remainder of 222.
Put 8 as the next digit of the answer. 
Result so far: 55458.319218
Subtract 7368 from 7590 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Moving on to step 15:
2220 divided by 921 is 2 with a remainder of 378.
Put 2 as the next digit of the answer. 
Result so far: 55458.3192182
Deduct 1842 from 2220 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

On to step 16:
If we divide 3780 by 921, we get 4 and a remainder of 96.
The number 4 becomes the next digit in our result. 
Result so far: 55458.31921824
Subtracting 3684 from 3780 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The quotient of the division is 55458.31921824, and the remainder is 9.6e-08.
