833859 ÷ 51 
The aim is to understand the frequency of 51 in 833859.

Going ahead to step 1:
8 divided by 51 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 51

On to step 2:
83 divided by 51 is 1 with a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 51 away from 83, we end up with 32.
Fetch the next digit (3) from the dividend, attach it to 32 and continue: 323 / 51

Let's proceed to step 3:
When dividing 323 by 51, we get 6 with a remainder of 17.
The next digit of our result is 6. 
Result so far: 16.0
Subtract 306 from 323 to get 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 51

Step 4:
178 divided by 51 is 3 with a remainder of 25.
The next digit of our result is 3. 
Result so far: 163.0
Subtract 153 from 178 to get 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 51

Step 5:
The number 51 fits into 255 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1635.0
Deduct 255 from 255 and we're left with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 51

Advancing to step 6:
When dividing 9 by 51, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 16350.0
Subtract 0 from 9 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
If we divide 90 by 51, we get 1 and a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 16350.1
The remainder is 39 after subtracting 51 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 8:
390 divided by 51 is 7 with a remainder of 33.
The next digit of our result is 7. 
Result so far: 16350.17
Subtract 357 from 390 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 9:
When dividing 330 by 51, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 16350.176
Subtract 306 from 330 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
If we divide 240 by 51, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 16350.1764
Subtracting 204 from 240 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
51 can be fit into 360 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 16350.17647
Deduct 357 from 360 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
If we divide 30 by 51, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 16350.17647
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
The number 51 fits into 300 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 16350.1764705
If we take 255 away from 300, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 14:
The number 51 fits into 450 8 times, leaving a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 16350.17647058
If we subtract 408 from 450, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 16350.17647058, with a leftover of 4.2e-08.
