Let's divide 364637 by 43
The aim is to understand the frequency of 43 in 364637.

On to step 1:
The number 43 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 43

Advancing to step 2:
When dividing 36 by 43, we get 0 with a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Bring next digit (4) of the dividend behind the 36 and repeat the process: 364 / 43

Moving on to step 3:
If we divide 364 by 43, we get 8 and a remainder of 20.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 344 from 364 and we're left with 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 43

Advancing to step 4:
43 goes into 206 4 times with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 84.0
If we take 172 away from 206, we end up with 34.
Take the next digit (3) from the dividend and append it to 34, then repeat: 343 / 43

Advancing to step 5:
If we divide 343 by 43, we get 7 and a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 847.0
Deduct 301 from 343 and we're left with 42.
Grab the next digit (7) from the dividend, add it to 42, then carry on: 427 / 43

Going ahead to step 6:
427 divided by 43 is 9 with a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 8479.0
If we subtract 387 from 427, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
43 can be fit into 400 9 times, resulting in a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 8479.9
The remainder is 13 after subtracting 387 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 8:
When dividing 130 by 43, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 8479.93
If we subtract 129 from 130, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
When dividing 10 by 43, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 8479.93
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
43 goes into 100 2 times with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 8479.9302
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
140 divided by 43 is 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 8479.93023
The remainder is 11 after subtracting 129 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 12:
If we divide 110 by 43, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 8479.930232
Subtract 86 from 110 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
43 can be fit into 240 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 8479.9302325
If we subtract 215 from 240, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 14:
When dividing 250 by 43, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 8479.93023255
Subtracting 215 from 250 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 8479.93023255 and a remainder of 3.5e-08.
