We divide 803720 by 43
The aim is to understand the frequency of 43 in 803720.

Advancing to step 1:
When dividing 8 by 43, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 43

On to step 2:
43 goes into 80 1 times with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 43 away from 80, we end up with 37.
Take the next digit (3) from the dividend and append it to 37, then repeat: 373 / 43

Going ahead to step 3:
When dividing 373 by 43, we get 8 with a remainder of 29.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 344 from 373 leaves us with 29.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 43

Advancing to step 4:
43 can be fit into 297 6 times, resulting in a remainder of 39.
Write down 6 as next digit of the result. 
Result so far: 186.0
If we subtract 258 from 297, we get 39.
Append the next digit (2) from the dividend to 39 and continue with: 392 / 43

Moving on to step 5:
43 can be fit into 392 9 times, resulting in a remainder of 5.
The next digit of our result is 9. 
Result so far: 1869.0
If we subtract 387 from 392, we get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 43

On to step 6:
The number 43 fits into 50 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 18691.0
If we take 43 away from 50, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
The number 43 fits into 70 1 times, leaving a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 18691.1
Deduct 43 from 70 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 8:
If we divide 270 by 43, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 18691.16
Deduct 258 from 270 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
The number 43 fits into 120 2 times, leaving a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 18691.162
The remainder is 34 after subtracting 86 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
43 can be fit into 340 7 times, resulting in a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 18691.1627
If we take 301 away from 340, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 11:
43 can be fit into 390 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 18691.16279
Subtract 387 from 390 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 12:
If we divide 30 by 43, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 18691.16279
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
When dividing 300 by 43, we get 6 with a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 18691.1627906
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 14:
When dividing 420 by 43, we get 9 with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 18691.16279069
Subtracting 387 from 420 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

After the division, we end up with 18691.16279069 and a remainder of 3.3e-08.
