We look at the division of 19090018 by 988 
The aim is to understand the frequency of 988 in 19090018.

On to step 1:
The number 988 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 988

Moving on to step 2:
When dividing 19 by 988, we get 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 988

Going ahead to step 3:
The number 988 fits into 190 0 times, leaving a remainder of 190.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 190 and we're left with 190.
Fetch the next digit (9) from the dividend, attach it to 190 and continue: 1909 / 988

Advancing to step 4:
988 can be fit into 1909 1 times, resulting in a remainder of 921.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 988 from 1909, we get 921.
Fetch the next digit (0) from the dividend, attach it to 921 and continue: 9210 / 988

Moving on to step 5:
988 can be fit into 9210 9 times, resulting in a remainder of 318.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 8892 from 9210 to get 318.
Fetch the next digit (0) from the dividend, attach it to 318 and continue: 3180 / 988

Let's proceed to step 6:
When dividing 3180 by 988, we get 3 with a remainder of 216.
Use 3 as the next digit of our solution. 
Result so far: 193.0
Subtract 2964 from 3180 to get 216.
Grab the next digit (1) from the dividend, add it to 216, then carry on: 2161 / 988

Advancing to step 7:
When dividing 2161 by 988, we get 2 with a remainder of 185.
Use 2 as the next digit of our solution. 
Result so far: 1932.0
If we take 1976 away from 2161, we end up with 185.
Bring next digit (8) of the dividend behind the 185 and repeat the process: 1858 / 988

On to step 8:
988 can be fit into 1858 1 times, resulting in a remainder of 870.
Put 1 as the next digit of the answer. 
Result so far: 19321.0
Subtracting 988 from 1858 leaves us with 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8700, and continue the process.

On to step 9:
988 goes into 8700 8 times with a remainder of 796.
Use 8 as the next digit of our solution. 
Result so far: 19321.8
Subtract 7904 from 8700 to get 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Let's proceed to step 10:
If we divide 7960 by 988, we get 8 and a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 19321.88
Deduct 7904 from 7960 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The quotient of the division is 19321.88, and the remainder is 0.056.
