We're dividing 75951428 by 61 
The aim is to understand the frequency of 61 in 75951428.

Going ahead to step 1:
The number 61 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 61

Advancing to step 2:
When dividing 75 by 61, we get 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 61 from 75, we get 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 61

On to step 3:
61 goes into 149 2 times with a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 122 away from 149, we end up with 27.
Fetch the next digit (5) from the dividend, attach it to 27 and continue: 275 / 61

Let's proceed to step 4:
61 can be fit into 275 4 times, resulting in a remainder of 31.
Write down 4 as next digit of the result. 
Result so far: 124.0
Subtracting 244 from 275 leaves us with 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 61

Going ahead to step 5:
The number 61 fits into 311 5 times, leaving a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 1245.0
Subtract 305 from 311 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 61

Advancing to step 6:
61 can be fit into 64 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 12451.0
Deduct 61 from 64 and we're left with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 61

Moving on to step 7:
When dividing 32 by 61, we get 0 with a remainder of 32.
The next digit of our result is 0. 
Result so far: 124510.0
The remainder is 32 after subtracting 0 from 32.
Include the next digit (8) from the dividend after 32, then repeat: 328 / 61

Going ahead to step 8:
If we divide 328 by 61, we get 5 and a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 1245105.0
Deduct 305 from 328 and we're left 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.

Advancing to step 9:
61 goes into 230 3 times with a remainder of 47.
The next digit of our result is 3. 
Result so far: 1245105.3
If we take 183 away from 230, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 10:
The number 61 fits into 470 7 times, leaving a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 1245105.37
The remainder is 43 after subtracting 427 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 11:
61 goes into 430 7 times with a remainder of 3.
The next digit of our result is 7. 
Result so far: 1245105.377
Subtract 427 from 430 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 1245105.377 with a remaining 0.0003.
