Let's divide 661035 by 51
The aim is to understand the frequency of 51 in 661035.

Step 1:
If we divide 6 by 51, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 51

Advancing to step 2:
When dividing 66 by 51, we get 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 51 from 66 to get 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 51

Let's proceed to step 3:
51 goes into 151 2 times with a remainder of 49.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 49 after subtracting 102 from 151.
Take the next digit (0) from the dividend and append it to 49, then repeat: 490 / 51

Let's proceed to step 4:
51 goes into 490 9 times with a remainder of 31.
The next digit of our result is 9. 
Result so far: 129.0
The remainder is 31 after subtracting 459 from 490.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 51

Advancing to step 5:
51 goes into 313 6 times with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 1296.0
Subtracting 306 from 313 leaves us with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 51

Going ahead to step 6:
75 divided by 51 is 1 with a remainder of 24.
The next digit of our result is 1. 
Result so far: 12961.0
If we subtract 51 from 75, we 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.

Moving on to step 7:
51 can be fit into 240 4 times, resulting in a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 12961.4
If we subtract 204 from 240, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
51 can be fit into 360 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 12961.47
Subtracting 357 from 360 leaves us 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 9:
51 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 12961.47
If we subtract 0 from 30, we 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 10:
When dividing 300 by 51, we get 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 12961.4705
Deduct 255 from 300 and we're left 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.

On to step 11:
450 divided by 51 is 8 with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 12961.47058
The remainder is 42 after subtracting 408 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
If we divide 420 by 51, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 12961.470588
If we subtract 408 from 420, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 12961.470588, and the remainder is 1.2e-06.
