60996321 ÷ 998 
The aim is to understand the frequency of 998 in 60996321.

On to step 1:
6 divided by 998 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 998

Advancing to step 2:
If we divide 60 by 998, we get 0 and a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Fetch the next digit (9) from the dividend, attach it to 60 and continue: 609 / 998

Moving on to step 3:
The number 998 fits into 609 0 times, leaving a remainder of 609.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 609 and we're left with 609.
Append the next digit (9) from the dividend to 609 and continue with: 6099 / 998

Advancing to step 4:
When dividing 6099 by 998, we get 6 with a remainder of 111.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 5988 from 6099 to get 111.
Take the next digit (6) from the dividend and append it to 111, then repeat: 1116 / 998

Going ahead to step 5:
998 goes into 1116 1 times with a remainder of 118.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Deduct 998 from 1116 and we're left with 118.
Bring next digit (3) of the dividend behind the 118 and repeat the process: 1183 / 998

Let's proceed to step 6:
When dividing 1183 by 998, we get 1 with a remainder of 185.
Write down 1 as next digit of the result. 
Result so far: 611.0
Subtract 998 from 1183 to get 185.
Bring next digit (2) of the dividend behind the 185 and repeat the process: 1852 / 998

Moving on to step 7:
998 can be fit into 1852 1 times, resulting in a remainder of 854.
Put 1 as the next digit of the answer. 
Result so far: 6111.0
If we subtract 998 from 1852, we get 854.
Bring next digit (1) of the dividend behind the 854 and repeat the process: 8541 / 998

Step 8:
The number 998 fits into 8541 8 times, leaving a remainder of 557.
Write down 8 as next digit of the result. 
Result so far: 61118.0
Subtract 7984 from 8541 to get 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Step 9:
When dividing 5570 by 998, we get 5 with a remainder of 580.
Use 5 as the next digit of our solution. 
Result so far: 61118.5
Subtracting 4990 from 5570 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 10:
If we divide 5800 by 998, we get 5 and a remainder of 810.
Write down 5 as next digit of the result. 
Result so far: 61118.55
Subtracting 4990 from 5800 leaves us with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

After the division, we end up with 61118.55 and a remainder of 0.81.
