99198411 ÷ 356 
The aim is to understand the frequency of 356 in 99198411.

Advancing to step 1:
If we divide 9 by 356, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 356

Moving on to step 2:
When dividing 99 by 356, we get 0 with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Append the next digit (1) from the dividend to 99 and continue with: 991 / 356

On to step 3:
991 divided by 356 is 2 with a remainder of 279.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 712 from 991 to get 279.
Take the next digit (9) from the dividend and append it to 279, then repeat: 2799 / 356

Advancing to step 4:
The number 356 fits into 2799 7 times, leaving a remainder of 307.
Write down 7 as next digit of the result. 
Result so far: 27.0
Deduct 2492 from 2799 and we're left with 307.
Bring next digit (8) of the dividend behind the 307 and repeat the process: 3078 / 356

On to step 5:
3078 divided by 356 is 8 with a remainder of 230.
The number 8 becomes the next digit in our result. 
Result so far: 278.0
If we take 2848 away from 3078, we end up with 230.
Take the next digit (4) from the dividend and append it to 230, then repeat: 2304 / 356

Going ahead to step 6:
If we divide 2304 by 356, we get 6 and a remainder of 168.
Put 6 as the next digit of the answer. 
Result so far: 2786.0
Deduct 2136 from 2304 and we're left with 168.
Take the next digit (1) from the dividend and append it to 168, then repeat: 1681 / 356

Let's proceed to step 7:
1681 divided by 356 is 4 with a remainder of 257.
Write down 4 as next digit of the result. 
Result so far: 27864.0
Subtracting 1424 from 1681 leaves us with 257.
Grab the next digit (1) from the dividend, add it to 257, then carry on: 2571 / 356

Moving on to step 8:
The number 356 fits into 2571 7 times, leaving a remainder of 79.
The next digit of our result is 7. 
Result so far: 278647.0
Subtract 2492 from 2571 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 9:
If we divide 790 by 356, we get 2 and a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 278647.2
Deduct 712 from 790 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 10:
When dividing 780 by 356, we get 2 with a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 278647.22
If we subtract 712 from 780, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The quotient of the division is 278647.22, and the remainder is 0.068.
