We're dividing 37173879 by 477 
The aim is to understand the frequency of 477 in 37173879.

On to step 1:
477 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 477

Moving on to step 2:
The number 477 fits into 37 0 times, leaving a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Take the next digit (1) from the dividend and append it to 37, then repeat: 371 / 477

Moving on to step 3:
477 can be fit into 371 0 times, resulting in a remainder of 371.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 371 and we're left with 371.
Grab the next digit (7) from the dividend, add it to 371, then carry on: 3717 / 477

Advancing to step 4:
The number 477 fits into 3717 7 times, leaving a remainder of 378.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 3339 from 3717 and we're left with 378.
Bring next digit (3) of the dividend behind the 378 and repeat the process: 3783 / 477

Moving on to step 5:
The number 477 fits into 3783 7 times, leaving a remainder of 444.
The next digit of our result is 7. 
Result so far: 77.0
Deduct 3339 from 3783 and we're left with 444.
Include the next digit (8) from the dividend after 444, then repeat: 4448 / 477

Moving on to step 6:
477 can be fit into 4448 9 times, resulting in a remainder of 155.
The number 9 becomes the next digit in our result. 
Result so far: 779.0
The remainder is 155 after subtracting 4293 from 4448.
Grab the next digit (7) from the dividend, add it to 155, then carry on: 1557 / 477

Going ahead to step 7:
477 goes into 1557 3 times with a remainder of 126.
The number 3 becomes the next digit in our result. 
Result so far: 7793.0
Subtracting 1431 from 1557 leaves us with 126.
Include the next digit (9) from the dividend after 126, then repeat: 1269 / 477

On to step 8:
When dividing 1269 by 477, we get 2 with a remainder of 315.
Record the quotient 2 as the next digit in the result. 
Result so far: 77932.0
If we take 954 away from 1269, we end up with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Going ahead to step 9:
The number 477 fits into 3150 6 times, leaving a remainder of 288.
Write down 6 as next digit of the result. 
Result so far: 77932.6
Subtract 2862 from 3150 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 10:
477 goes into 2880 6 times with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 77932.66
If we subtract 2862 from 2880, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 77932.66 with a remaining 0.018.
