The aim is to understand the frequency of 936 in 12821954.

On to step 1:
1 divided by 936 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 936

Moving on to step 2:
936 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 936

Going ahead to step 3:
If we divide 128 by 936, we get 0 and a remainder of 128.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 128 and we're left with 128.
Grab the next digit (2) from the dividend, add it to 128, then carry on: 1282 / 936

On to step 4:
1282 divided by 936 is 1 with a remainder of 346.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 346 after subtracting 936 from 1282.

Going ahead to step 5:
936 goes into 3461 3 times with a remainder of 653.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 653 after subtracting 2808 from 3461.
Take the next digit (9) from the dividend and append it to 653, then repeat: 6539 / 936

Step 6:
The number 936 fits into 6539 6 times, leaving a remainder of 923.
Put 6 as the next digit of the answer. 
Result so far: 136.0
If we take 5616 away from 6539, we end up with 923.
Fetch the next digit (5) from the dividend, attach it to 923 and continue: 9235 / 936

Advancing to step 7:
If we divide 9235 by 936, we get 9 and a remainder of 811.
The number 9 becomes the next digit in our result. 
Result so far: 1369.0
Deduct 8424 from 9235 and we're left with 811.
Fetch the next digit (4) from the dividend, attach it to 811 and continue: 8114 / 936

Going ahead to step 8:
The number 936 fits into 8114 8 times, leaving a remainder of 626.
Write down 8 as next digit of the result. 
Result so far: 13698.0
If we subtract 7488 from 8114, we get 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 9:
If we divide 6260 by 936, we get 6 and a remainder of 644.
The number 6 becomes the next digit in our result. 
Result so far: 13698.6
If we subtract 5616 from 6260, we get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Going ahead to step 10:
6440 divided by 936 is 6 with a remainder of 824.
Put 6 as the next digit of the answer. 
Result so far: 13698.66
Subtracting 5616 from 6440 leaves us with 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

In conclusion, the division gives 13698.66 with a balance of 0.824.
