We divide 90666307 by 371
The aim is to understand the frequency of 371 in 90666307.

On to step 1:
The number 371 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 371

Advancing to step 2:
371 goes into 90 0 times with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Fetch the next digit (6) from the dividend, attach it to 90 and continue: 906 / 371

Advancing to step 3:
If we divide 906 by 371, we get 2 and a remainder of 164.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 164 after subtracting 742 from 906.
Fetch the next digit (6) from the dividend, attach it to 164 and continue: 1646 / 371

Step 4:
When dividing 1646 by 371, we get 4 with a remainder of 162.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we subtract 1484 from 1646, we get 162.
Grab the next digit (6) from the dividend, add it to 162, then carry on: 1626 / 371

Step 5:
371 can be fit into 1626 4 times, resulting in a remainder of 142.
Use 4 as the next digit of our solution. 
Result so far: 244.0
If we subtract 1484 from 1626, we get 142.
Take the next digit (3) from the dividend and append it to 142, then repeat: 1423 / 371

Moving on to step 6:
The number 371 fits into 1423 3 times, leaving a remainder of 310.
Put 3 as the next digit of the answer. 
Result so far: 2443.0
Deduct 1113 from 1423 and we're left with 310.
Append the next digit (0) from the dividend to 310 and continue with: 3100 / 371

On to step 7:
3100 divided by 371 is 8 with a remainder of 132.
Put 8 as the next digit of the answer. 
Result so far: 24438.0
If we take 2968 away from 3100, we end up with 132.
Grab the next digit (7) from the dividend, add it to 132, then carry on: 1327 / 371

Moving on to step 8:
When dividing 1327 by 371, we get 3 with a remainder of 214.
Use 3 as the next digit of our solution. 
Result so far: 244383.0
Deduct 1113 from 1327 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 9:
If we divide 2140 by 371, we get 5 and a remainder of 285.
Put 5 as the next digit of the answer. 
Result so far: 244383.5
The remainder is 285 after subtracting 1855 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 10:
If we divide 2850 by 371, we get 7 and a remainder of 253.
Put 7 as the next digit of the answer. 
Result so far: 244383.57
The remainder is 253 after subtracting 2597 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Step 11:
The number 371 fits into 2530 6 times, leaving a remainder of 304.
The number 6 becomes the next digit in our result. 
Result so far: 244383.576
Subtract 2226 from 2530 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 12:
The number 371 fits into 3040 8 times, leaving a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 244383.5768
Deduct 2968 from 3040 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 13:
720 divided by 371 is 1 with a remainder of 349.
Put 1 as the next digit of the answer. 
Result so far: 244383.57681
Deduct 371 from 720 and we're left with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Moving on to step 14:
3490 divided by 371 is 9 with a remainder of 151.
Put 9 as the next digit of the answer. 
Result so far: 244383.576819
If we subtract 3339 from 3490, we get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Going ahead to step 15:
371 goes into 1510 4 times with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 244383.5768194
If we take 1484 away from 1510, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 16:
260 divided by 371 is 0 with a remainder of 260.
Put 0 as the next digit of the answer. 
Result so far: 244383.5768194
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

In conclusion, the division gives 244383.5768194 with a balance of 2.6e-07.
