We look at the division of 86998083 by 848 
The aim is to understand the frequency of 848 in 86998083.

Step 1:
When dividing 8 by 848, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 848

On to step 2:
848 can be fit into 86 0 times, resulting in a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Take the next digit (9) from the dividend and append it to 86, then repeat: 869 / 848

Going ahead to step 3:
848 goes into 869 1 times with a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 848 from 869 and we're left with 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 848

Let's proceed to step 4:
If we divide 219 by 848, we get 0 and a remainder of 219.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 219 after subtracting 0 from 219.
Bring next digit (8) of the dividend behind the 219 and repeat the process: 2198 / 848

Let's proceed to step 5:
848 goes into 2198 2 times with a remainder of 502.
The next digit of our result is 2. 
Result so far: 102.0
If we subtract 1696 from 2198, we get 502.
Bring next digit (0) of the dividend behind the 502 and repeat the process: 5020 / 848

On to step 6:
If we divide 5020 by 848, we get 5 and a remainder of 780.
Write down 5 as next digit of the result. 
Result so far: 1025.0
Subtracting 4240 from 5020 leaves us with 780.
Include the next digit (8) from the dividend after 780, then repeat: 7808 / 848

Going ahead to step 7:
If we divide 7808 by 848, we get 9 and a remainder of 176.
Use 9 as the next digit of our solution. 
Result so far: 10259.0
Subtract 7632 from 7808 to get 176.
Fetch the next digit (3) from the dividend, attach it to 176 and continue: 1763 / 848

Step 8:
1763 divided by 848 is 2 with a remainder of 67.
The next digit of our result is 2. 
Result so far: 102592.0
Subtract 1696 from 1763 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 9:
848 can be fit into 670 0 times, resulting in a remainder of 670.
Put 0 as the next digit of the answer. 
Result so far: 102592.0
Deduct 0 from 670 and we're left with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Moving on to step 10:
If we divide 6700 by 848, we get 7 and a remainder of 764.
Put 7 as the next digit of the answer. 
Result so far: 102592.07
Subtracting 5936 from 6700 leaves us with 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

On to step 11:
When dividing 7640 by 848, we get 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 102592.079
If we subtract 7632 from 7640, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
When dividing 80 by 848, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 102592.079
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
If we divide 800 by 848, we get 0 and a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 102592.079
Subtract 0 from 800 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The final outcome is 102592.079, with a leftover of 0.0008.
