We're dividing 91345877 by 298 
The aim is to understand the frequency of 298 in 91345877.

Going ahead to step 1:
9 divided by 298 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 298

Going ahead to step 2:
When dividing 91 by 298, we get 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Take the next digit (3) from the dividend and append it to 91, then repeat: 913 / 298

Going ahead to step 3:
298 goes into 913 3 times with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 19 after subtracting 894 from 913.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 298

On to step 4:
194 divided by 298 is 0 with a remainder of 194.
The next digit of our result is 0. 
Result so far: 30.0
Subtract 0 from 194 to get 194.
Grab the next digit (5) from the dividend, add it to 194, then carry on: 1945 / 298

Step 5:
1945 divided by 298 is 6 with a remainder of 157.
Put 6 as the next digit of the answer. 
Result so far: 306.0
Subtracting 1788 from 1945 leaves us with 157.
Bring next digit (8) of the dividend behind the 157 and repeat the process: 1578 / 298

Step 6:
The number 298 fits into 1578 5 times, leaving a remainder of 88.
Use 5 as the next digit of our solution. 
Result so far: 3065.0
Subtracting 1490 from 1578 leaves us with 88.
Bring next digit (7) of the dividend behind the 88 and repeat the process: 887 / 298

Step 7:
298 can be fit into 887 2 times, resulting in a remainder of 291.
The number 2 becomes the next digit in our result. 
Result so far: 30652.0
Deduct 596 from 887 and we're left with 291.
Include the next digit (7) from the dividend after 291, then repeat: 2917 / 298

On to step 8:
2917 divided by 298 is 9 with a remainder of 235.
Put 9 as the next digit of the answer. 
Result so far: 306529.0
The remainder is 235 after subtracting 2682 from 2917.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Going ahead to step 9:
If we divide 2350 by 298, we get 7 and a remainder of 264.
Put 7 as the next digit of the answer. 
Result so far: 306529.7
Subtract 2086 from 2350 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 10:
If we divide 2640 by 298, we get 8 and a remainder of 256.
The number 8 becomes the next digit in our result. 
Result so far: 306529.78
If we subtract 2384 from 2640, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 11:
2560 divided by 298 is 8 with a remainder of 176.
Write down 8 as next digit of the result. 
Result so far: 306529.788
Deduct 2384 from 2560 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

After the division, we end up with 306529.788 and a remainder of 0.0176.
