Let's divide 921941 by 51
The aim is to understand the frequency of 51 in 921941.

On to step 1:
51 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 51

On to step 2:
92 divided by 51 is 1 with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 51 away from 92, we end up with 41.
Include the next digit (1) from the dividend after 41, then repeat: 411 / 51

On to step 3:
51 can be fit into 411 8 times, resulting in a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 18.0
The remainder is 3 after subtracting 408 from 411.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 51

Let's proceed to step 4:
If we divide 39 by 51, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 180.0
If we subtract 0 from 39, we get 39.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 51

Moving on to step 5:
51 can be fit into 394 7 times, resulting in a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 1807.0
Subtract 357 from 394 to get 37.
Grab the next digit (1) from the dividend, add it to 37, then carry on: 371 / 51

Going ahead to step 6:
51 can be fit into 371 7 times, resulting in a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 18077.0
If we take 357 away from 371, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
51 goes into 140 2 times with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 18077.2
Deduct 102 from 140 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
When dividing 380 by 51, we get 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 18077.27
Subtracting 357 from 380 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
230 divided by 51 is 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 18077.274
The remainder is 26 after subtracting 204 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
260 divided by 51 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 18077.2745
Deduct 255 from 260 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
51 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 18077.2745
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
The number 51 fits into 500 9 times, leaving a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 18077.274509
If we subtract 459 from 500, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 13:
The number 51 fits into 410 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 18077.2745098
If we take 408 away from 410, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
51 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 18077.2745098
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 18077.2745098, with a leftover of 2e-08.
