We're dividing 11233975 by 170 
The aim is to understand the frequency of 170 in 11233975.

On to step 1:
1 divided by 170 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 170

Going ahead to step 2:
If we divide 11 by 170, we get 0 and a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 170

Let's proceed to step 3:
If we divide 112 by 170, we get 0 and a remainder of 112.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 112 leaves us with 112.
Include the next digit (3) from the dividend after 112, then repeat: 1123 / 170

Moving on to step 4:
When dividing 1123 by 170, we get 6 with a remainder of 103.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 1020 away from 1123, we end up with 103.
Bring next digit (3) of the dividend behind the 103 and repeat the process: 1033 / 170

Let's proceed to step 5:
170 can be fit into 1033 6 times, resulting in a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
If we subtract 1020 from 1033, we get 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 170

On to step 6:
The number 170 fits into 139 0 times, leaving a remainder of 139.
Put 0 as the next digit of the answer. 
Result so far: 660.0
Subtracting 0 from 139 leaves us with 139.
Fetch the next digit (7) from the dividend, attach it to 139 and continue: 1397 / 170

Step 7:
170 goes into 1397 8 times with a remainder of 37.
Write down 8 as next digit of the result. 
Result so far: 6608.0
Deduct 1360 from 1397 and we're left with 37.
Append the next digit (5) from the dividend to 37 and continue with: 375 / 170

Going ahead to step 8:
375 divided by 170 is 2 with a remainder of 35.
The number 2 becomes the next digit in our result. 
Result so far: 66082.0
Subtracting 340 from 375 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
170 goes into 350 2 times with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 66082.2
If we subtract 340 from 350, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
170 goes into 100 0 times with a remainder of 100.
The next digit of our result is 0. 
Result so far: 66082.2
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
The number 170 fits into 1000 5 times, leaving a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 66082.205
If we subtract 850 from 1000, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 12:
170 goes into 1500 8 times with a remainder of 140.
The number 8 becomes the next digit in our result. 
Result so far: 66082.2058
If we take 1360 away from 1500, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 13:
170 can be fit into 1400 8 times, resulting in a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 66082.20588
The remainder is 40 after subtracting 1360 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 66082.20588 and a remainder of 4e-05.
