We look at the division of 727135 by 61 
The aim is to understand the frequency of 61 in 727135.

On 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
Subtracting 0 from 7 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 61

Advancing to step 2:
72 divided by 61 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 61 away from 72, we end up with 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 61

On to step 3:
61 can be fit into 117 1 times, resulting in a remainder of 56.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 61 from 117, we get 56.
Append the next digit (1) from the dividend to 56 and continue with: 561 / 61

On to step 4:
61 can be fit into 561 9 times, resulting in a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 119.0
The remainder is 12 after subtracting 549 from 561.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 61

Advancing to step 5:
The number 61 fits into 123 2 times, leaving a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 1192.0
If we take 122 away from 123, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 61

Going ahead to step 6:
When dividing 15 by 61, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 11920.0
If we take 0 away from 15, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
If we divide 150 by 61, we get 2 and a remainder of 28.
The next digit of our result is 2. 
Result so far: 11920.2
Deduct 122 from 150 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
When dividing 280 by 61, we get 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 11920.24
Deduct 244 from 280 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
61 goes into 360 5 times with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 11920.245
If we take 305 away from 360, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 10:
61 goes into 550 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 11920.2459
Subtracting 549 from 550 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 11:
If we divide 10 by 61, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 11920.2459
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
When dividing 100 by 61, we get 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 11920.245901
The remainder is 39 after subtracting 61 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 13:
If we divide 390 by 61, we get 6 and a remainder of 24.
The next digit of our result is 6. 
Result so far: 11920.2459016
Deduct 366 from 390 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
If we divide 240 by 61, we get 3 and a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 11920.24590163
Deduct 183 from 240 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The quotient of the division is 11920.24590163, and the remainder is 5.7e-08.
