We're dividing 618899 by 61 
The aim is to understand the frequency of 61 in 618899.

Moving on to step 1:
If we divide 6 by 61, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 61

Going ahead to step 2:
The number 61 fits into 61 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 61 from 61 leaves us with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 61

On to step 3:
61 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 8, we get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 61

Advancing to step 4:
When dividing 88 by 61, we get 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 101.0
If we subtract 61 from 88, we get 27.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 61

Going ahead to step 5:
When dividing 279 by 61, we get 4 with a remainder of 35.
Put 4 as the next digit of the answer. 
Result so far: 1014.0
Subtract 244 from 279 to get 35.
Bring next digit (9) of the dividend behind the 35 and repeat the process: 359 / 61

Step 6:
61 goes into 359 5 times with a remainder of 54.
Put 5 as the next digit of the answer. 
Result so far: 10145.0
Subtracting 305 from 359 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 7:
If we divide 540 by 61, we get 8 and a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 10145.8
If we subtract 488 from 540, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 8:
The number 61 fits into 520 8 times, leaving a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 10145.88
If we take 488 away from 520, 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.

The final outcome is 10145.88, with a leftover of 0.032.
