Let's divide 90899128 by 107
The aim is to understand the frequency of 107 in 90899128.

Step 1:
If we divide 9 by 107, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 107

On to step 2:
107 can be fit into 90 0 times, resulting in a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Append the next digit (8) from the dividend to 90 and continue with: 908 / 107

Going ahead to step 3:
107 goes into 908 8 times with a remainder of 52.
The next digit of our result is 8. 
Result so far: 8.0
If we take 856 away from 908, we end up with 52.
Include the next digit (9) from the dividend after 52, then repeat: 529 / 107

Moving on to step 4:
When dividing 529 by 107, we get 4 with a remainder of 101.
Put 4 as the next digit of the answer. 
Result so far: 84.0
Subtract 428 from 529 to get 101.
Take the next digit (9) from the dividend and append it to 101, then repeat: 1019 / 107

On to step 5:
107 can be fit into 1019 9 times, resulting in a remainder of 56.
The number 9 becomes the next digit in our result. 
Result so far: 849.0
Subtract 963 from 1019 to get 56.
Include the next digit (1) from the dividend after 56, then repeat: 561 / 107

On to step 6:
107 goes into 561 5 times with a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 8495.0
The remainder is 26 after subtracting 535 from 561.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 107

On to step 7:
262 divided by 107 is 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 84952.0
Subtracting 214 from 262 leaves us with 48.
Bring next digit (8) of the dividend behind the 48 and repeat the process: 488 / 107

Let's proceed to step 8:
When dividing 488 by 107, we get 4 with a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 849524.0
If we take 428 away from 488, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
600 divided by 107 is 5 with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 849524.5
Subtracting 535 from 600 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 10:
650 divided by 107 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 849524.56
Deduct 642 from 650 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
107 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 849524.56
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 12:
107 goes into 800 7 times with a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 849524.5607
Subtracting 749 from 800 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 13:
The number 107 fits into 510 4 times, leaving a remainder of 82.
Use 4 as the next digit of our solution. 
Result so far: 849524.56074
Subtracting 428 from 510 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 14:
107 can be fit into 820 7 times, resulting in a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 849524.560747
Deduct 749 from 820 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 15:
When dividing 710 by 107, we get 6 with a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 849524.5607476
The remainder is 68 after subtracting 642 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 16:
107 can be fit into 680 6 times, resulting in a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 849524.56074766
Deduct 642 from 680 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 849524.56074766, with a leftover of 3.8e-08.
