We're dividing 18628905 by 959 
The aim is to understand the frequency of 959 in 18628905.

On to step 1:
If we divide 1 by 959, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 959

Let's proceed to step 2:
18 divided by 959 is 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 959

Step 3:
186 divided by 959 is 0 with a remainder of 186.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 186 and we're left with 186.
Fetch the next digit (2) from the dividend, attach it to 186 and continue: 1862 / 959

On to step 4:
If we divide 1862 by 959, we get 1 and a remainder of 903.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 959 from 1862 leaves us with 903.
Bring next digit (8) of the dividend behind the 903 and repeat the process: 9038 / 959

Let's proceed to step 5:
9038 divided by 959 is 9 with a remainder of 407.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 8631 from 9038 leaves us with 407.
Include the next digit (9) from the dividend after 407, then repeat: 4079 / 959

Let's proceed to step 6:
959 goes into 4079 4 times with a remainder of 243.
Record the quotient 4 as the next digit in the result. 
Result so far: 194.0
Deduct 3836 from 4079 and we're left with 243.
Include the next digit (0) from the dividend after 243, then repeat: 2430 / 959

Advancing to step 7:
When dividing 2430 by 959, we get 2 with a remainder of 512.
The next digit of our result is 2. 
Result so far: 1942.0
Deduct 1918 from 2430 and we're left with 512.
Include the next digit (5) from the dividend after 512, then repeat: 5125 / 959

Let's proceed to step 8:
When dividing 5125 by 959, we get 5 with a remainder of 330.
Record the quotient 5 as the next digit in the result. 
Result so far: 19425.0
Subtracting 4795 from 5125 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 9:
The number 959 fits into 3300 3 times, leaving a remainder of 423.
Record the quotient 3 as the next digit in the result. 
Result so far: 19425.3
Subtract 2877 from 3300 to get 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Advancing to step 10:
If we divide 4230 by 959, we get 4 and a remainder of 394.
The next digit of our result is 4. 
Result so far: 19425.34
If we subtract 3836 from 4230, we get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Moving on to step 11:
3940 divided by 959 is 4 with a remainder of 104.
Record the quotient 4 as the next digit in the result. 
Result so far: 19425.344
Deduct 3836 from 3940 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The quotient of the division is 19425.344, and the remainder is 0.0104.
