Let's divide 33815401 by 371
The aim is to understand the frequency of 371 in 33815401.

Let's proceed to step 1:
If we divide 3 by 371, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 371

Let's proceed to step 2:
371 goes into 33 0 times with a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Grab the next digit (8) from the dividend, add it to 33, then carry on: 338 / 371

Moving on to step 3:
When dividing 338 by 371, we get 0 with a remainder of 338.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 338 after subtracting 0 from 338.
Bring next digit (1) of the dividend behind the 338 and repeat the process: 3381 / 371

Advancing to step 4:
When dividing 3381 by 371, we get 9 with a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 3339 away from 3381, we end up with 42.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 371

Moving on to step 5:
371 can be fit into 425 1 times, resulting in a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
If we subtract 371 from 425, we get 54.
Include the next digit (4) from the dividend after 54, then repeat: 544 / 371

On to step 6:
If we divide 544 by 371, we get 1 and a remainder of 173.
The number 1 becomes the next digit in our result. 
Result so far: 911.0
If we take 371 away from 544, we end up with 173.
Bring next digit (0) of the dividend behind the 173 and repeat the process: 1730 / 371

Advancing to step 7:
The number 371 fits into 1730 4 times, leaving a remainder of 246.
The next digit of our result is 4. 
Result so far: 9114.0
Deduct 1484 from 1730 and we're left with 246.
Include the next digit (1) from the dividend after 246, then repeat: 2461 / 371

Advancing to step 8:
If we divide 2461 by 371, we get 6 and a remainder of 235.
The next digit of our result is 6. 
Result so far: 91146.0
Subtract 2226 from 2461 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 9:
371 goes into 2350 6 times with a remainder of 124.
The number 6 becomes the next digit in our result. 
Result so far: 91146.6
Subtracting 2226 from 2350 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 10:
The number 371 fits into 1240 3 times, leaving a remainder of 127.
The next digit of our result is 3. 
Result so far: 91146.63
Deduct 1113 from 1240 and we're left with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Going ahead to step 11:
371 can be fit into 1270 3 times, resulting in a remainder of 157.
Put 3 as the next digit of the answer. 
Result so far: 91146.633
Deduct 1113 from 1270 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Our division results in 91146.633 with a remaining 0.0157.
