Let's divide 98742987 by 427
The aim is to understand the frequency of 427 in 98742987.

Going ahead to step 1:
The number 427 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 427

On to step 2:
427 goes into 98 0 times with a remainder of 98.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 98 after subtracting 0 from 98.
Take the next digit (7) from the dividend and append it to 98, then repeat: 987 / 427

Going ahead to step 3:
When dividing 987 by 427, we get 2 with a remainder of 133.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 854 from 987 and we're left with 133.
Include the next digit (4) from the dividend after 133, then repeat: 1334 / 427

Step 4:
When dividing 1334 by 427, we get 3 with a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtract 1281 from 1334 to get 53.
Append the next digit (2) from the dividend to 53 and continue with: 532 / 427

Advancing to step 5:
The number 427 fits into 532 1 times, leaving a remainder of 105.
Use 1 as the next digit of our solution. 
Result so far: 231.0
Subtracting 427 from 532 leaves us with 105.
Include the next digit (9) from the dividend after 105, then repeat: 1059 / 427

Advancing to step 6:
If we divide 1059 by 427, we get 2 and a remainder of 205.
Record the quotient 2 as the next digit in the result. 
Result so far: 2312.0
If we subtract 854 from 1059, we get 205.
Fetch the next digit (8) from the dividend, attach it to 205 and continue: 2058 / 427

On to step 7:
427 goes into 2058 4 times with a remainder of 350.
The next digit of our result is 4. 
Result so far: 23124.0
Subtract 1708 from 2058 to get 350.
Bring next digit (7) of the dividend behind the 350 and repeat the process: 3507 / 427

Advancing to step 8:
427 can be fit into 3507 8 times, resulting in a remainder of 91.
The next digit of our result is 8. 
Result so far: 231248.0
Subtract 3416 from 3507 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 9:
If we divide 910 by 427, we get 2 and a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 231248.2
If we subtract 854 from 910, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
The number 427 fits into 560 1 times, leaving a remainder of 133.
Use 1 as the next digit of our solution. 
Result so far: 231248.21
Subtracting 427 from 560 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 11:
427 can be fit into 1330 3 times, resulting in a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 231248.213
Subtracting 1281 from 1330 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 12:
427 goes into 490 1 times with a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 231248.2131
The remainder is 63 after subtracting 427 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 13:
427 can be fit into 630 1 times, resulting in a remainder of 203.
The next digit of our result is 1. 
Result so far: 231248.21311
If we take 427 away from 630, we end up with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

The quotient of the division is 231248.21311, and the remainder is 0.000203.
