We divide 51457187 by 171
The aim is to understand the frequency of 171 in 51457187.

Step 1:
The number 171 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 171

Going ahead to step 2:
The number 171 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Grab the next digit (4) from the dividend, add it to 51, then carry on: 514 / 171

Advancing to step 3:
The number 171 fits into 514 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 513 away from 514, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 171

Advancing to step 4:
If we divide 15 by 171, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Deduct 0 from 15 and we're left with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 171

On to step 5:
When dividing 157 by 171, we get 0 with a remainder of 157.
Record the quotient 0 as the next digit in the result. 
Result so far: 300.0
If we subtract 0 from 157, we get 157.
Grab the next digit (1) from the dividend, add it to 157, then carry on: 1571 / 171

Let's proceed to step 6:
If we divide 1571 by 171, we get 9 and a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 3009.0
The remainder is 32 after subtracting 1539 from 1571.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 171

Moving on to step 7:
171 can be fit into 328 1 times, resulting in a remainder of 157.
The next digit of our result is 1. 
Result so far: 30091.0
Deduct 171 from 328 and we're left with 157.
Take the next digit (7) from the dividend and append it to 157, then repeat: 1577 / 171

Step 8:
The number 171 fits into 1577 9 times, leaving a remainder of 38.
The next digit of our result is 9. 
Result so far: 300919.0
Subtract 1539 from 1577 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
If we divide 380 by 171, we get 2 and a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 300919.2
If we subtract 342 from 380, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
The number 171 fits into 380 2 times, leaving a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 300919.22
The remainder is 38 after subtracting 342 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 300919.22 with a remaining 0.038.
