We're dividing 9643080 by 371 
The aim is to understand the frequency of 371 in 9643080.

Advancing to step 1:
When dividing 9 by 371, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 371

Let's proceed to step 2:
If we divide 96 by 371, we get 0 and a remainder of 96.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 96 leaves us with 96.
Append the next digit (4) from the dividend to 96 and continue with: 964 / 371

Let's proceed to step 3:
964 divided by 371 is 2 with a remainder of 222.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 742 away from 964, we end up with 222.
Grab the next digit (3) from the dividend, add it to 222, then carry on: 2223 / 371

On to step 4:
2223 divided by 371 is 5 with a remainder of 368.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Deduct 1855 from 2223 and we're left with 368.
Include the next digit (0) from the dividend after 368, then repeat: 3680 / 371

Going ahead to step 5:
371 goes into 3680 9 times with a remainder of 341.
Record the quotient 9 as the next digit in the result. 
Result so far: 259.0
Subtract 3339 from 3680 to get 341.
Fetch the next digit (8) from the dividend, attach it to 341 and continue: 3418 / 371

Going ahead to step 6:
If we divide 3418 by 371, we get 9 and a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 2599.0
Deduct 3339 from 3418 and we're left with 79.
Grab the next digit (0) from the dividend, add it to 79, then carry on: 790 / 371

Going ahead to step 7:
790 divided by 371 is 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 25992.0
If we subtract 742 from 790, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 8:
The number 371 fits into 480 1 times, leaving a remainder of 109.
Put 1 as the next digit of the answer. 
Result so far: 25992.1
If we subtract 371 from 480, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 9:
When dividing 1090 by 371, we get 2 with a remainder of 348.
Record the quotient 2 as the next digit in the result. 
Result so far: 25992.12
If we subtract 742 from 1090, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Step 10:
3480 divided by 371 is 9 with a remainder of 141.
The number 9 becomes the next digit in our result. 
Result so far: 25992.129
Subtract 3339 from 3480 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Let's proceed to step 11:
If we divide 1410 by 371, we get 3 and a remainder of 297.
Write down 3 as next digit of the result. 
Result so far: 25992.1293
If we subtract 1113 from 1410, we get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Going ahead to step 12:
2970 divided by 371 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 25992.12938
Subtract 2968 from 2970 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
If we divide 20 by 371, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 25992.12938
If we subtract 0 from 20, 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 14:
The number 371 fits into 200 0 times, leaving a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 25992.12938
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 25992.12938, with a leftover of 2e-06.
