We look at the division of 91644900 by 959 
The aim is to understand the frequency of 959 in 91644900.

Moving on to step 1:
959 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 959

Let's proceed to step 2:
The number 959 fits into 91 0 times, leaving a remainder of 91.
Use 0 as the next digit of our solution. 
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

Going ahead to step 3:
If we divide 916 by 959, we get 0 and a remainder of 916.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 916, we end up with 916.
Append the next digit (4) from the dividend to 916 and continue with: 9164 / 959

Moving on to step 4:
959 can be fit into 9164 9 times, resulting in a remainder of 533.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 8631 from 9164 and we're left with 533.
Take the next digit (4) from the dividend and append it to 533, then repeat: 5334 / 959

Moving on to step 5:
The number 959 fits into 5334 5 times, leaving a remainder of 539.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
Deduct 4795 from 5334 and we're left with 539.
Bring next digit (9) of the dividend behind the 539 and repeat the process: 5399 / 959

Going ahead to step 6:
The number 959 fits into 5399 5 times, leaving a remainder of 604.
The number 5 becomes the next digit in our result. 
Result so far: 955.0
If we take 4795 away from 5399, we end up with 604.
Take the next digit (0) from the dividend and append it to 604, then repeat: 6040 / 959

Advancing to step 7:
959 can be fit into 6040 6 times, resulting in a remainder of 286.
The number 6 becomes the next digit in our result. 
Result so far: 9556.0
The remainder is 286 after subtracting 5754 from 6040.
Fetch the next digit (0) from the dividend, attach it to 286 and continue: 2860 / 959

Moving on to step 8:
When dividing 2860 by 959, we get 2 with a remainder of 942.
Put 2 as the next digit of the answer. 
Result so far: 95562.0
Subtract 1918 from 2860 to get 942.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9420, and continue the process.

Advancing to step 9:
The number 959 fits into 9420 9 times, leaving a remainder of 789.
Put 9 as the next digit of the answer. 
Result so far: 95562.9
Subtract 8631 from 9420 to get 789.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7890, and continue the process.

Step 10:
959 goes into 7890 8 times with a remainder of 218.
The next digit of our result is 8. 
Result so far: 95562.98
The remainder is 218 after subtracting 7672 from 7890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Moving on to step 11:
When dividing 2180 by 959, we get 2 with a remainder of 262.
Put 2 as the next digit of the answer. 
Result so far: 95562.982
Subtracting 1918 from 2180 leaves us with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Advancing to step 12:
2620 divided by 959 is 2 with a remainder of 702.
Record the quotient 2 as the next digit in the result. 
Result so far: 95562.9822
Subtract 1918 from 2620 to get 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

The final result is 95562.9822 with a remainder of 0.00702.
