We look at the division of 42936220 by 959 
The aim is to understand the frequency of 959 in 42936220.

Moving on to step 1:
If we divide 4 by 959, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 959

Advancing to step 2:
959 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 959

Moving on to step 3:
The number 959 fits into 429 0 times, leaving a remainder of 429.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 429 leaves us with 429.
Fetch the next digit (3) from the dividend, attach it to 429 and continue: 4293 / 959

Going ahead to step 4:
959 goes into 4293 4 times with a remainder of 457.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 3836 from 4293 to get 457.
Fetch the next digit (6) from the dividend, attach it to 457 and continue: 4576 / 959

Step 5:
If we divide 4576 by 959, we get 4 and a remainder of 740.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we take 3836 away from 4576, we end up with 740.
Take the next digit (2) from the dividend and append it to 740, then repeat: 7402 / 959

Moving on to step 6:
7402 divided by 959 is 7 with a remainder of 689.
The next digit of our result is 7. 
Result so far: 447.0
Subtracting 6713 from 7402 leaves us with 689.
Bring next digit (2) of the dividend behind the 689 and repeat the process: 6892 / 959

On to step 7:
6892 divided by 959 is 7 with a remainder of 179.
Put 7 as the next digit of the answer. 
Result so far: 4477.0
The remainder is 179 after subtracting 6713 from 6892.
Append the next digit (0) from the dividend to 179 and continue with: 1790 / 959

Moving on to step 8:
1790 divided by 959 is 1 with a remainder of 831.
Write down 1 as next digit of the result. 
Result so far: 44771.0
If we take 959 away from 1790, we end up with 831.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8310, and continue the process.

Step 9:
When dividing 8310 by 959, we get 8 with a remainder of 638.
The next digit of our result is 8. 
Result so far: 44771.8
If we take 7672 away from 8310, we end up with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Going ahead to step 10:
6380 divided by 959 is 6 with a remainder of 626.
Put 6 as the next digit of the answer. 
Result so far: 44771.86
Subtracting 5754 from 6380 leaves us with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Step 11:
If we divide 6260 by 959, we get 6 and a remainder of 506.
Use 6 as the next digit of our solution. 
Result so far: 44771.866
If we take 5754 away from 6260, we end up with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

After the division, we end up with 44771.866 and a remainder of 0.0506.
