We're dividing 748425 by 61 
The aim is to understand the frequency of 61 in 748425.

Going ahead to step 1:
The number 61 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 61

On to step 2:
74 divided by 61 is 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 61 from 74 and we're left with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 61

Moving on to step 3:
The number 61 fits into 138 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 122 away from 138, we end up with 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 61

On to step 4:
When dividing 164 by 61, we get 2 with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
Deduct 122 from 164 and we're left with 42.
Bring next digit (2) of the dividend behind the 42 and repeat the process: 422 / 61

Advancing to step 5:
422 divided by 61 is 6 with a remainder of 56.
The next digit of our result is 6. 
Result so far: 1226.0
If we subtract 366 from 422, we get 56.
Include the next digit (5) from the dividend after 56, then repeat: 565 / 61

On to step 6:
The number 61 fits into 565 9 times, leaving a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 12269.0
If we subtract 549 from 565, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
If we divide 160 by 61, we get 2 and a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 12269.2
Subtract 122 from 160 to 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 8:
When dividing 380 by 61, we get 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 12269.26
If we take 366 away from 380, we end up 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.

Advancing to step 9:
61 can be fit into 140 2 times, resulting in a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 12269.262
Deduct 122 from 140 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
61 goes into 180 2 times with a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 12269.2622
Deduct 122 from 180 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Our division results in 12269.2622 with a remaining 0.00058.
