We look at the division of 89026623 by 371 
The aim is to understand the frequency of 371 in 89026623.

On to step 1:
371 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 371

On to step 2:
When dividing 89 by 371, we get 0 with a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Grab the next digit (0) from the dividend, add it to 89, then carry on: 890 / 371

Moving on to step 3:
371 can be fit into 890 2 times, resulting in a remainder of 148.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 742 from 890 to get 148.
Include the next digit (2) from the dividend after 148, then repeat: 1482 / 371

On to step 4:
371 goes into 1482 3 times with a remainder of 369.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we subtract 1113 from 1482, we get 369.
Bring next digit (6) of the dividend behind the 369 and repeat the process: 3696 / 371

Advancing to step 5:
3696 divided by 371 is 9 with a remainder of 357.
The number 9 becomes the next digit in our result. 
Result so far: 239.0
If we take 3339 away from 3696, we end up with 357.
Fetch the next digit (6) from the dividend, attach it to 357 and continue: 3576 / 371

Moving on to step 6:
If we divide 3576 by 371, we get 9 and a remainder of 237.
Put 9 as the next digit of the answer. 
Result so far: 2399.0
The remainder is 237 after subtracting 3339 from 3576.
Bring next digit (2) of the dividend behind the 237 and repeat the process: 2372 / 371

Advancing to step 7:
371 can be fit into 2372 6 times, resulting in a remainder of 146.
Write down 6 as next digit of the result. 
Result so far: 23996.0
Subtract 2226 from 2372 to get 146.
Bring next digit (3) of the dividend behind the 146 and repeat the process: 1463 / 371

Step 8:
When dividing 1463 by 371, we get 3 with a remainder of 350.
Record the quotient 3 as the next digit in the result. 
Result so far: 239963.0
If we take 1113 away from 1463, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 9:
371 goes into 3500 9 times with a remainder of 161.
Write down 9 as next digit of the result. 
Result so far: 239963.9
Subtract 3339 from 3500 to get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Going ahead to step 10:
371 goes into 1610 4 times with a remainder of 126.
Write down 4 as next digit of the result. 
Result so far: 239963.94
If we take 1484 away from 1610, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 11:
The number 371 fits into 1260 3 times, leaving a remainder of 147.
Record the quotient 3 as the next digit in the result. 
Result so far: 239963.943
If we subtract 1113 from 1260, we get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Let's proceed to step 12:
1470 divided by 371 is 3 with a remainder of 357.
Use 3 as the next digit of our solution. 
Result so far: 239963.9433
Subtract 1113 from 1470 to get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Our division results in 239963.9433 with a remaining 0.00357.
