We look at the division of 39100402 by 170 
The aim is to understand the frequency of 170 in 39100402.

Going ahead to step 1:
170 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 170

Moving on to step 2:
The number 170 fits into 39 0 times, leaving a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 170

Step 3:
170 can be fit into 391 2 times, resulting in a remainder of 51.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 51 after subtracting 340 from 391.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 170

On to step 4:
170 can be fit into 510 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 0 after subtracting 510 from 510.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 170

Let's proceed to step 5:
If we divide 0 by 170, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 230.0
Deduct 0 from 0 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 170

Advancing to step 6:
170 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 2300.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 170

Let's proceed to step 7:
40 divided by 170 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 23000.0
The remainder is 40 after subtracting 0 from 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 170

Step 8:
When dividing 402 by 170, we get 2 with a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 230002.0
The remainder is 62 after subtracting 340 from 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 9:
When dividing 620 by 170, we get 3 with a remainder of 110.
Write down 3 as next digit of the result. 
Result so far: 230002.3
The remainder is 110 after subtracting 510 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 10:
When dividing 1100 by 170, we get 6 with a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 230002.36
Subtract 1020 from 1100 to 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 11:
800 divided by 170 is 4 with a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 230002.364
Subtracting 680 from 800 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
170 goes into 1200 7 times with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 230002.3647
Subtracting 1190 from 1200 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
170 can be fit into 100 0 times, resulting in a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 230002.3647
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 14:
170 can be fit into 1000 5 times, resulting in a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 230002.364705
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.

On to step 15:
170 can be fit into 1500 8 times, resulting in a remainder of 140.
Write down 8 as next digit of the result. 
Result so far: 230002.3647058
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.

Moving on to step 16:
170 goes into 1400 8 times with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 230002.36470588
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.

The quotient of the division is 230002.36470588, and the remainder is 4e-08.
