18793520 ÷ 959 
The aim is to understand the frequency of 959 in 18793520.

Advancing to step 1:
959 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 959

Step 2:
If we divide 18 by 959, we get 0 and a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 959

Advancing to step 3:
The number 959 fits into 187 0 times, leaving a remainder of 187.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 187, we end up with 187.
Bring next digit (9) of the dividend behind the 187 and repeat the process: 1879 / 959

Going ahead to step 4:
When dividing 1879 by 959, we get 1 with a remainder of 920.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 959 from 1879 leaves us with 920.
Fetch the next digit (3) from the dividend, attach it to 920 and continue: 9203 / 959

Advancing to step 5:
959 can be fit into 9203 9 times, resulting in a remainder of 572.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we take 8631 away from 9203, we end up with 572.
Take the next digit (5) from the dividend and append it to 572, then repeat: 5725 / 959

On to step 6:
The number 959 fits into 5725 5 times, leaving a remainder of 930.
Use 5 as the next digit of our solution. 
Result so far: 195.0
Deduct 4795 from 5725 and we're left with 930.
Fetch the next digit (2) from the dividend, attach it to 930 and continue: 9302 / 959

Step 7:
When dividing 9302 by 959, we get 9 with a remainder of 671.
Write down 9 as next digit of the result. 
Result so far: 1959.0
Subtract 8631 from 9302 to get 671.
Include the next digit (0) from the dividend after 671, then repeat: 6710 / 959

Moving on to step 8:
When dividing 6710 by 959, we get 6 with a remainder of 956.
The next digit of our result is 6. 
Result so far: 19596.0
Subtract 5754 from 6710 to get 956.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9560, and continue the process.

On to step 9:
959 can be fit into 9560 9 times, resulting in a remainder of 929.
Record the quotient 9 as the next digit in the result. 
Result so far: 19596.9
Deduct 8631 from 9560 and we're left with 929.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9290, and continue the process.

Step 10:
When dividing 9290 by 959, we get 9 with a remainder of 659.
The number 9 becomes the next digit in our result. 
Result so far: 19596.99
If we subtract 8631 from 9290, we get 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

The final result is 19596.99 with a remainder of 0.659.
