Let's divide 563837 by 51
The aim is to understand the frequency of 51 in 563837.

Going ahead to step 1:
If we divide 5 by 51, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 51

Going ahead to step 2:
If we divide 56 by 51, we get 1 and a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 51 from 56 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 51

Let's proceed to step 3:
If we divide 53 by 51, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 51 from 53 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 51

Advancing to step 4:
51 goes into 28 0 times with a remainder of 28.
The next digit of our result is 0. 
Result so far: 110.0
If we take 0 away from 28, we end up with 28.
Include the next digit (3) from the dividend after 28, then repeat: 283 / 51

Advancing to step 5:
When dividing 283 by 51, we get 5 with a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 1105.0
Subtract 255 from 283 to get 28.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 51

Going ahead to step 6:
287 divided by 51 is 5 with a remainder of 32.
Put 5 as the next digit of the answer. 
Result so far: 11055.0
If we take 255 away from 287, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
The number 51 fits into 320 6 times, leaving a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 11055.6
Deduct 306 from 320 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 8:
The number 51 fits into 140 2 times, leaving a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 11055.62
If we subtract 102 from 140, we get 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 9:
If we divide 380 by 51, we get 7 and a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 11055.627
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.

Going ahead to step 10:
51 goes into 230 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 11055.6274
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.

Advancing to step 11:
260 divided by 51 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 11055.62745
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.

Advancing to step 12:
When dividing 50 by 51, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 11055.62745
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
51 goes into 500 9 times with a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 11055.6274509
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.

Step 14:
51 goes into 410 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 11055.62745098
Deduct 408 from 410 and we're left 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.

After the division, we end up with 11055.62745098 and a remainder of 2e-09.
