We look at the division of 63655310 by 371 
The aim is to understand the frequency of 371 in 63655310.

Going ahead to step 1:
371 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 371

Moving on to step 2:
If we divide 63 by 371, we get 0 and a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Fetch the next digit (6) from the dividend, attach it to 63 and continue: 636 / 371

Moving on to step 3:
636 divided by 371 is 1 with a remainder of 265.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 371 from 636 leaves us with 265.
Grab the next digit (5) from the dividend, add it to 265, then carry on: 2655 / 371

Advancing to step 4:
If we divide 2655 by 371, we get 7 and a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 2597 from 2655 to get 58.
Include the next digit (5) from the dividend after 58, then repeat: 585 / 371

Let's proceed to step 5:
371 can be fit into 585 1 times, resulting in a remainder of 214.
The next digit of our result is 1. 
Result so far: 171.0
If we take 371 away from 585, we end up with 214.
Append the next digit (3) from the dividend to 214 and continue with: 2143 / 371

Advancing to step 6:
The number 371 fits into 2143 5 times, leaving a remainder of 288.
The next digit of our result is 5. 
Result so far: 1715.0
If we subtract 1855 from 2143, we get 288.
Include the next digit (1) from the dividend after 288, then repeat: 2881 / 371

On to step 7:
371 goes into 2881 7 times with a remainder of 284.
The number 7 becomes the next digit in our result. 
Result so far: 17157.0
If we subtract 2597 from 2881, we get 284.
Grab the next digit (0) from the dividend, add it to 284, then carry on: 2840 / 371

Step 8:
The number 371 fits into 2840 7 times, leaving a remainder of 243.
The next digit of our result is 7. 
Result so far: 171577.0
The remainder is 243 after subtracting 2597 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

On to step 9:
371 can be fit into 2430 6 times, resulting in a remainder of 204.
The number 6 becomes the next digit in our result. 
Result so far: 171577.6
If we subtract 2226 from 2430, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 10:
371 goes into 2040 5 times with a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 171577.65
If we subtract 1855 from 2040, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 11:
If we divide 1850 by 371, we get 4 and a remainder of 366.
The number 4 becomes the next digit in our result. 
Result so far: 171577.654
Subtracting 1484 from 1850 leaves us with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Advancing to step 12:
3660 divided by 371 is 9 with a remainder of 321.
Use 9 as the next digit of our solution. 
Result so far: 171577.6549
If we take 3339 away from 3660, we end up with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Advancing to step 13:
If we divide 3210 by 371, we get 8 and a remainder of 242.
Record the quotient 8 as the next digit in the result. 
Result so far: 171577.65498
Subtract 2968 from 3210 to get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Moving on to step 14:
371 can be fit into 2420 6 times, resulting in a remainder of 194.
The number 6 becomes the next digit in our result. 
Result so far: 171577.654986
Subtract 2226 from 2420 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 15:
When dividing 1940 by 371, we get 5 with a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 171577.6549865
If we subtract 1855 from 1940, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 16:
When dividing 850 by 371, we get 2 with a remainder of 108.
Record the quotient 2 as the next digit in the result. 
Result so far: 171577.65498652
If we subtract 742 from 850, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Our division results in 171577.65498652 with a remaining 1.08e-07.
