121935 divided by 89 
The aim is to understand the frequency of 89 in 121935.

Going ahead to step 1:
1 divided by 89 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 89

Going ahead to step 2:
The number 89 fits into 12 0 times, leaving a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 89

Moving on to step 3:
89 can be fit into 121 1 times, resulting in a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 89 from 121 to get 32.
Bring next digit (9) of the dividend behind the 32 and repeat the process: 329 / 89

Going ahead to step 4:
The number 89 fits into 329 3 times, leaving a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 267 from 329 and we're left with 62.
Include the next digit (3) from the dividend after 62, then repeat: 623 / 89

Step 5:
623 divided by 89 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
Subtract 623 from 623 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 89

Advancing to step 6:
If we divide 5 by 89, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution.

Deduct 0 from 5 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
If we divide 50 by 89, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 1370.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
89 goes into 500 5 times with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 1370.05
Deduct 445 from 500 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
89 goes into 550 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 1370.056
Subtracting 534 from 550 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
The number 89 fits into 160 1 times, leaving a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 1370.0561
Subtract 89 from 160 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 11:
89 can be fit into 710 7 times, resulting in a remainder of 87.
The number 7 becomes the next digit in our result. 
Result so far: 1370.05617
Subtracting 623 from 710 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 12:
89 goes into 870 9 times with a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 1370.056179
Deduct 801 from 870 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 13:
If we divide 690 by 89, we get 7 and a remainder of 67.
The next digit of our result is 7. 
Result so far: 1370.0561797
Subtracting 623 from 690 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 14:
670 divided by 89 is 7 with a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 1370.05617977
Subtracting 623 from 670 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Our division results in 1370.05617977 with a remaining 4.7e-08.
