We're dividing 891749 by 51 
The aim is to understand the frequency of 51 in 891749.

Let's proceed to step 1:
If we divide 8 by 51, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 51

On to step 2:
51 can be fit into 89 1 times, resulting in a remainder of 38.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 51 from 89 and we're left with 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 51

Advancing to step 3:
381 divided by 51 is 7 with a remainder of 24.
The next digit of our result is 7. 
Result so far: 17.0
If we take 357 away from 381, we end up with 24.
Grab the next digit (7) from the dividend, add it to 24, then carry on: 247 / 51

Moving on to step 4:
If we divide 247 by 51, we get 4 and a remainder of 43.
The next digit of our result is 4. 
Result so far: 174.0
Subtract 204 from 247 to get 43.
Bring next digit (4) of the dividend behind the 43 and repeat the process: 434 / 51

Moving on to step 5:
When dividing 434 by 51, we get 8 with a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 1748.0
Subtract 408 from 434 to get 26.
Bring next digit (9) of the dividend behind the 26 and repeat the process: 269 / 51

Moving on to step 6:
The number 51 fits into 269 5 times, leaving a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 17485.0
Deduct 255 from 269 and we're left 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.

Moving on to step 7:
140 divided by 51 is 2 with a remainder of 38.
The next digit of our result is 2. 
Result so far: 17485.2
If we take 102 away from 140, we end up 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:
51 can be fit into 380 7 times, resulting in a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 17485.27
If we subtract 357 from 380, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 9:
51 goes into 230 4 times with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 17485.274
Deduct 204 from 230 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
51 can be fit into 260 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 17485.2745
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.

Let's proceed to step 11:
50 divided by 51 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 17485.2745
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.

Let's proceed to step 12:
51 goes into 500 9 times with a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 17485.274509
Deduct 459 from 500 and we're left with 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.
The number 8 becomes the next digit in our result. 
Result so far: 17485.2745098
The remainder is 2 after subtracting 408 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
51 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 17485.2745098
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 17485.2745098 and a remainder of 2e-08.
