We divide 91662604 by 959
The aim is to understand the frequency of 959 in 91662604.

Going ahead to step 1:
959 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 959

On to step 2:
91 divided by 959 is 0 with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Take the next digit (6) from the dividend and append it to 91, then repeat: 916 / 959

On to step 3:
916 divided by 959 is 0 with a remainder of 916.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 916 after subtracting 0 from 916.
Append the next digit (6) from the dividend to 916 and continue with: 9166 / 959

Let's proceed to step 4:
959 goes into 9166 9 times with a remainder of 535.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 8631 from 9166 leaves us with 535.
Grab the next digit (2) from the dividend, add it to 535, then carry on: 5352 / 959

On to step 5:
959 can be fit into 5352 5 times, resulting in a remainder of 557.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
The remainder is 557 after subtracting 4795 from 5352.
Include the next digit (6) from the dividend after 557, then repeat: 5576 / 959

Advancing to step 6:
959 can be fit into 5576 5 times, resulting in a remainder of 781.
Record the quotient 5 as the next digit in the result. 
Result so far: 955.0
The remainder is 781 after subtracting 4795 from 5576.
Grab the next digit (0) from the dividend, add it to 781, then carry on: 7810 / 959

Step 7:
959 goes into 7810 8 times with a remainder of 138.
Put 8 as the next digit of the answer. 
Result so far: 9558.0
Subtract 7672 from 7810 to get 138.
Include the next digit (4) from the dividend after 138, then repeat: 1384 / 959

Advancing to step 8:
When dividing 1384 by 959, we get 1 with a remainder of 425.
Write down 1 as next digit of the result. 
Result so far: 95581.0
Subtract 959 from 1384 to get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Step 9:
The number 959 fits into 4250 4 times, leaving a remainder of 414.
The next digit of our result is 4. 
Result so far: 95581.4
If we subtract 3836 from 4250, we get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Let's proceed to step 10:
959 goes into 4140 4 times with a remainder of 304.
The next digit of our result is 4. 
Result so far: 95581.44
If we take 3836 away from 4140, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

After the division, we end up with 95581.44 and a remainder of 0.304.
