We're dividing 19151071 by 988 
The aim is to understand the frequency of 988 in 19151071.

Advancing to step 1:
The number 988 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 988

On to step 2:
19 divided by 988 is 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 988

Going ahead to step 3:
988 can be fit into 191 0 times, resulting in a remainder of 191.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 191, we end up with 191.
Bring next digit (5) of the dividend behind the 191 and repeat the process: 1915 / 988

Step 4:
When dividing 1915 by 988, we get 1 with a remainder of 927.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 988 from 1915 to get 927.
Append the next digit (1) from the dividend to 927 and continue with: 9271 / 988

Let's proceed to step 5:
If we divide 9271 by 988, we get 9 and a remainder of 379.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 8892 from 9271 to get 379.
Fetch the next digit (0) from the dividend, attach it to 379 and continue: 3790 / 988

Advancing to step 6:
The number 988 fits into 3790 3 times, leaving a remainder of 826.
Use 3 as the next digit of our solution. 
Result so far: 193.0
The remainder is 826 after subtracting 2964 from 3790.
Take the next digit (7) from the dividend and append it to 826, then repeat: 8267 / 988

Advancing to step 7:
8267 divided by 988 is 8 with a remainder of 363.
Put 8 as the next digit of the answer. 
Result so far: 1938.0
Subtract 7904 from 8267 to get 363.
Include the next digit (1) from the dividend after 363, then repeat: 3631 / 988

Moving on to step 8:
If we divide 3631 by 988, we get 3 and a remainder of 667.
Use 3 as the next digit of our solution. 
Result so far: 19383.0
If we take 2964 away from 3631, we end up with 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

Step 9:
988 goes into 6670 6 times with a remainder of 742.
Record the quotient 6 as the next digit in the result. 
Result so far: 19383.6
Subtract 5928 from 6670 to get 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Step 10:
When dividing 7420 by 988, we get 7 with a remainder of 504.
Put 7 as the next digit of the answer. 
Result so far: 19383.67
Deduct 6916 from 7420 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Moving on to step 11:
The number 988 fits into 5040 5 times, leaving a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 19383.675
Deduct 4940 from 5040 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 12:
988 goes into 1000 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 19383.6751
Subtracting 988 from 1000 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
120 divided by 988 is 0 with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 19383.6751
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 14:
988 goes into 1200 1 times with a remainder of 212.
Record the quotient 1 as the next digit in the result. 
Result so far: 19383.675101
If we subtract 988 from 1200, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 15:
988 goes into 2120 2 times with a remainder of 144.
Record the quotient 2 as the next digit in the result. 
Result so far: 19383.6751012
If we take 1976 away from 2120, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 16:
The number 988 fits into 1440 1 times, leaving a remainder of 452.
Put 1 as the next digit of the answer. 
Result so far: 19383.67510121
Subtract 988 from 1440 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

The final result is 19383.67510121 with a remainder of 4.52e-07.
