We're dividing 836710 by 51 
The aim is to understand the frequency of 51 in 836710.

Going ahead to step 1:
8 divided by 51 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 51

Going ahead to step 2:
The number 51 fits into 83 1 times, leaving a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 51 from 83 leaves us with 32.
Take the next digit (6) from the dividend and append it to 32, then repeat: 326 / 51

Advancing to step 3:
51 goes into 326 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we subtract 306 from 326, we get 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 51

Going ahead to step 4:
When dividing 207 by 51, we get 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 164.0
If we take 204 away from 207, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 51

On to step 5:
51 goes into 31 0 times with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 1640.0
Subtracting 0 from 31 leaves us with 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 51

Let's proceed to step 6:
310 divided by 51 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 16406.0
The remainder is 4 after subtracting 306 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
The number 51 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 16406.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
51 goes into 400 7 times with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 16406.07
If we subtract 357 from 400, we 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 9:
When dividing 430 by 51, we get 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 16406.078
Deduct 408 from 430 and we're left 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.

Moving on to step 10:
If we divide 220 by 51, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 16406.0784
Subtracting 204 from 220 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
51 can be fit into 160 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 16406.07843
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.

Step 12:
The number 51 fits into 70 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 16406.078431
Deduct 51 from 70 and we're left 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.

Step 13:
51 goes into 190 3 times with a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 16406.0784313
If we subtract 153 from 190, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 14:
The number 51 fits into 370 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 16406.07843137
If we subtract 357 from 370, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 16406.07843137 with a remainder of 1.3e-08.
