52120157 ÷ 956 
The aim is to understand the frequency of 956 in 52120157.

Moving on to step 1:
956 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 956

Going ahead to step 2:
956 can be fit into 52 0 times, resulting in a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Take the next digit (1) from the dividend and append it to 52, then repeat: 521 / 956

Step 3:
521 divided by 956 is 0 with a remainder of 521.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 521, we end up with 521.
Bring next digit (2) of the dividend behind the 521 and repeat the process: 5212 / 956

On to step 4:
If we divide 5212 by 956, we get 5 and a remainder of 432.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 4780 away from 5212, we end up with 432.
Append the next digit (0) from the dividend to 432 and continue with: 4320 / 956

On to step 5:
956 can be fit into 4320 4 times, resulting in a remainder of 496.
Write down 4 as next digit of the result. 
Result so far: 54.0
If we take 3824 away from 4320, we end up with 496.
Take the next digit (1) from the dividend and append it to 496, then repeat: 4961 / 956

Advancing to step 6:
If we divide 4961 by 956, we get 5 and a remainder of 181.
Put 5 as the next digit of the answer. 
Result so far: 545.0
Subtract 4780 from 4961 to get 181.
Bring next digit (5) of the dividend behind the 181 and repeat the process: 1815 / 956

Moving on to step 7:
956 goes into 1815 1 times with a remainder of 859.
Put 1 as the next digit of the answer. 
Result so far: 5451.0
If we take 956 away from 1815, we end up with 859.
Grab the next digit (7) from the dividend, add it to 859, then carry on: 8597 / 956

On to step 8:
The number 956 fits into 8597 8 times, leaving a remainder of 949.
Record the quotient 8 as the next digit in the result. 
Result so far: 54518.0
The remainder is 949 after subtracting 7648 from 8597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9490, and continue the process.

Moving on to step 9:
956 goes into 9490 9 times with a remainder of 886.
The number 9 becomes the next digit in our result. 
Result so far: 54518.9
If we subtract 8604 from 9490, we get 886.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8860, and continue the process.

Moving on to step 10:
956 can be fit into 8860 9 times, resulting in a remainder of 256.
Write down 9 as next digit of the result. 
Result so far: 54518.99
Deduct 8604 from 8860 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

In conclusion, the division gives 54518.99 with a balance of 0.256.
