83413984 divided by 170 
The aim is to understand the frequency of 170 in 83413984.

Moving on to step 1:
8 divided by 170 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 170

Moving on to step 2:
If we divide 83 by 170, we get 0 and a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Append the next digit (4) from the dividend to 83 and continue with: 834 / 170

Advancing to step 3:
If we divide 834 by 170, we get 4 and a remainder of 154.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 680 from 834 to get 154.
Grab the next digit (1) from the dividend, add it to 154, then carry on: 1541 / 170

Going ahead to step 4:
If we divide 1541 by 170, we get 9 and a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 49.0
Deduct 1530 from 1541 and we're left with 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 170

Let's proceed to step 5:
170 can be fit into 113 0 times, resulting in a remainder of 113.
The number 0 becomes the next digit in our result. 
Result so far: 490.0
Subtract 0 from 113 to get 113.
Include the next digit (9) from the dividend after 113, then repeat: 1139 / 170

Advancing to step 6:
If we divide 1139 by 170, we get 6 and a remainder of 119.
Write down 6 as next digit of the result. 
Result so far: 4906.0
Subtracting 1020 from 1139 leaves us with 119.
Take the next digit (8) from the dividend and append it to 119, then repeat: 1198 / 170

Moving on to step 7:
170 goes into 1198 7 times with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 49067.0
If we take 1190 away from 1198, we end up with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 170

Moving on to step 8:
When dividing 84 by 170, we get 0 with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 490670.0
Subtracting 0 from 84 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 9:
170 goes into 840 4 times with a remainder of 160.
The number 4 becomes the next digit in our result. 
Result so far: 490670.4
If we take 680 away from 840, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 10:
170 can be fit into 1600 9 times, resulting in a remainder of 70.
Put 9 as the next digit of the answer. 
Result so far: 490670.49
If we subtract 1530 from 1600, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 11:
700 divided by 170 is 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 490670.494
If we subtract 680 from 700, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
If we divide 200 by 170, we get 1 and a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 490670.4941
The remainder is 30 after subtracting 170 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
The number 170 fits into 300 1 times, leaving a remainder of 130.
The next digit of our result is 1. 
Result so far: 490670.49411
Deduct 170 from 300 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final outcome is 490670.49411, with a leftover of 0.00013.
