53890358 divided by 170 
The aim is to understand the frequency of 170 in 53890358.

Step 1:
170 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 170

Step 2:
53 divided by 170 is 0 with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Bring next digit (8) of the dividend behind the 53 and repeat the process: 538 / 170

Let's proceed to step 3:
If we divide 538 by 170, we get 3 and a remainder of 28.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 28 after subtracting 510 from 538.
Grab the next digit (9) from the dividend, add it to 28, then carry on: 289 / 170

Advancing to step 4:
170 can be fit into 289 1 times, resulting in a remainder of 119.
The next digit of our result is 1. 
Result so far: 31.0
Deduct 170 from 289 and we're left with 119.
Take the next digit (0) from the dividend and append it to 119, then repeat: 1190 / 170

On to step 5:
1190 divided by 170 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 317.0
Subtract 1190 from 1190 to get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 170

Moving on to step 6:
3 divided by 170 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 3170.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 170

Let's proceed to step 7:
35 divided by 170 is 0 with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 31700.0
If we take 0 away from 35, we end up with 35.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 170

On to step 8:
When dividing 358 by 170, we get 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 317002.0
If we take 340 away from 358, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
170 goes into 180 1 times with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 317002.1
If we take 170 away from 180, we end up 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.

Step 10:
170 goes into 100 0 times with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 317002.1
Deduct 0 from 100 and we're left 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.

Moving on to step 11:
If we divide 1000 by 170, we get 5 and a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 317002.105
Subtract 850 from 1000 to 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 12:
The number 170 fits into 1500 8 times, leaving a remainder of 140.
Record the quotient 8 as the next digit in the result. 
Result so far: 317002.1058
Subtracting 1360 from 1500 leaves us 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.

Step 13:
If we divide 1400 by 170, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 317002.10588
If we take 1360 away from 1400, we end up with 40.
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 317002.10588 and a remainder of 4e-05.
