856180 ÷ 51 
The aim is to understand the frequency of 51 in 856180.

Moving on to step 1:
51 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 51

Going ahead to step 2:
When dividing 85 by 51, we get 1 with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 34 after subtracting 51 from 85.
Fetch the next digit (6) from the dividend, attach it to 34 and continue: 346 / 51

Going ahead to step 3:
346 divided by 51 is 6 with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 40 after subtracting 306 from 346.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 51

Advancing to step 4:
When dividing 401 by 51, we get 7 with a remainder of 44.
Write down 7 as next digit of the result. 
Result so far: 167.0
If we take 357 away from 401, we end up with 44.
Bring next digit (8) of the dividend behind the 44 and repeat the process: 448 / 51

Going ahead to step 5:
448 divided by 51 is 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 1678.0
The remainder is 40 after subtracting 408 from 448.
Grab the next digit (0) from the dividend, add it to 40, then carry on: 400 / 51

Advancing to step 6:
When dividing 400 by 51, we get 7 with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 16787.0
Subtract 357 from 400 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
When dividing 430 by 51, we get 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 16787.8
Subtracting 408 from 430 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
If we divide 220 by 51, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 16787.84
Subtract 204 from 220 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
The number 51 fits into 160 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 16787.843
If we take 153 away from 160, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 10:
When dividing 70 by 51, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 16787.8431
If we take 51 away from 70, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 11:
51 can be fit into 190 3 times, resulting in a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 16787.84313
The remainder is 37 after subtracting 153 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 12:
When dividing 370 by 51, we get 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 16787.843137
If we take 357 away from 370, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 13:
The number 51 fits into 130 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 16787.8431372
Subtract 102 from 130 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 14:
When dividing 280 by 51, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 16787.84313725
The remainder is 25 after subtracting 255 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 16787.84313725, with a leftover of 2.5e-08.
