988545 ÷ 61 
The aim is to understand the frequency of 61 in 988545.

Moving on to step 1:
If we divide 9 by 61, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 61

On to step 2:
61 can be fit into 98 1 times, resulting in a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 37 after subtracting 61 from 98.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 61

On to step 3:
The number 61 fits into 378 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 366 from 378 to get 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 61

Step 4:
61 can be fit into 125 2 times, resulting in a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 162.0
Deduct 122 from 125 and we're left with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 61

Advancing to step 5:
If we divide 34 by 61, we get 0 and a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 1620.0
The remainder is 34 after subtracting 0 from 34.
Take the next digit (5) from the dividend and append it to 34, then repeat: 345 / 61

Moving on to step 6:
345 divided by 61 is 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 16205.0
Deduct 305 from 345 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 7:
When dividing 400 by 61, we get 6 with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 16205.6
Subtracting 366 from 400 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
61 can be fit into 340 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 16205.65
Subtracting 305 from 340 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
61 goes into 350 5 times with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 16205.655
Deduct 305 from 350 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.

The quotient of the division is 16205.655, and the remainder is 0.0045.
