98560787 ÷ 170 
The aim is to understand the frequency of 170 in 98560787.

Step 1:
170 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 170

Moving on to step 2:
When dividing 98 by 170, we get 0 with a remainder of 98.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Include the next digit (5) from the dividend after 98, then repeat: 985 / 170

Moving on to step 3:
The number 170 fits into 985 5 times, leaving a remainder of 135.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 850 from 985, we get 135.
Append the next digit (6) from the dividend to 135 and continue with: 1356 / 170

On to step 4:
If we divide 1356 by 170, we get 7 and a remainder of 166.
Use 7 as the next digit of our solution. 
Result so far: 57.0
If we take 1190 away from 1356, we end up with 166.
Grab the next digit (0) from the dividend, add it to 166, then carry on: 1660 / 170

Let's proceed to step 5:
170 goes into 1660 9 times with a remainder of 130.
Write down 9 as next digit of the result. 
Result so far: 579.0
If we subtract 1530 from 1660, we get 130.
Grab the next digit (7) from the dividend, add it to 130, then carry on: 1307 / 170

Moving on to step 6:
The number 170 fits into 1307 7 times, leaving a remainder of 117.
Write down 7 as next digit of the result. 
Result so far: 5797.0
Subtract 1190 from 1307 to get 117.
Include the next digit (8) from the dividend after 117, then repeat: 1178 / 170

Advancing to step 7:
If we divide 1178 by 170, we get 6 and a remainder of 158.
Record the quotient 6 as the next digit in the result. 
Result so far: 57976.0
Deduct 1020 from 1178 and we're left with 158.
Append the next digit (7) from the dividend to 158 and continue with: 1587 / 170

On to step 8:
1587 divided by 170 is 9 with a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 579769.0
The remainder is 57 after subtracting 1530 from 1587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 9:
170 goes into 570 3 times with a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 579769.3
The remainder is 60 after subtracting 510 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
170 can be fit into 600 3 times, resulting in a remainder of 90.
Put 3 as the next digit of the answer. 
Result so far: 579769.33
Subtract 510 from 600 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Our division results in 579769.33 with a remaining 0.09.
