We're dividing 43421054 by 794 
The aim is to understand the frequency of 794 in 43421054.

On to step 1:
4 divided by 794 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 794

On to step 2:
794 goes into 43 0 times with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (4) from the dividend, attach it to 43 and continue: 434 / 794

Moving on to step 3:
The number 794 fits into 434 0 times, leaving a remainder of 434.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 434, we end up with 434.
Fetch the next digit (2) from the dividend, attach it to 434 and continue: 4342 / 794

Moving on to step 4:
If we divide 4342 by 794, we get 5 and a remainder of 372.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 3970 from 4342 and we're left with 372.
Bring next digit (1) of the dividend behind the 372 and repeat the process: 3721 / 794

Advancing to step 5:
3721 divided by 794 is 4 with a remainder of 545.
The next digit of our result is 4. 
Result so far: 54.0
The remainder is 545 after subtracting 3176 from 3721.
Grab the next digit (0) from the dividend, add it to 545, then carry on: 5450 / 794

Moving on to step 6:
5450 divided by 794 is 6 with a remainder of 686.
Record the quotient 6 as the next digit in the result. 
Result so far: 546.0
Deduct 4764 from 5450 and we're left with 686.
Append the next digit (5) from the dividend to 686 and continue with: 6865 / 794

Step 7:
794 can be fit into 6865 8 times, resulting in a remainder of 513.
Use 8 as the next digit of our solution. 
Result so far: 5468.0
If we take 6352 away from 6865, we end up with 513.
Grab the next digit (4) from the dividend, add it to 513, then carry on: 5134 / 794

Going ahead to step 8:
5134 divided by 794 is 6 with a remainder of 370.
Use 6 as the next digit of our solution. 
Result so far: 54686.0
Subtracting 4764 from 5134 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 9:
The number 794 fits into 3700 4 times, leaving a remainder of 524.
The number 4 becomes the next digit in our result. 
Result so far: 54686.4
Subtract 3176 from 3700 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Going ahead to step 10:
794 goes into 5240 6 times with a remainder of 476.
The number 6 becomes the next digit in our result. 
Result so far: 54686.46
If we take 4764 away from 5240, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Let's proceed to step 11:
794 goes into 4760 5 times with a remainder of 790.
Put 5 as the next digit of the answer. 
Result so far: 54686.465
If we take 3970 away from 4760, we end up with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Moving on to step 12:
The number 794 fits into 7900 9 times, leaving a remainder of 754.
The next digit of our result is 9. 
Result so far: 54686.4659
Deduct 7146 from 7900 and we're left with 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Going ahead to step 13:
7540 divided by 794 is 9 with a remainder of 394.
Write down 9 as next digit of the result. 
Result so far: 54686.46599
If we take 7146 away from 7540, we end up with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

The final outcome is 54686.46599, with a leftover of 0.000394.
