Advancing to step 3:
420 divided by 43 is 9 with a remainder of 33.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 387 from 420 to get 33.
Append the next digit (9) from the dividend to 33 and continue with: 339 / 43

Advancing to step 4:
If we divide 339 by 43, we get 7 and a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 97.0
The remainder is 38 after subtracting 301 from 339.
Include the next digit (0) from the dividend after 38, then repeat: 380 / 43

Going ahead to step 5:
43 goes into 380 8 times with a remainder of 36.
The next digit of our result is 8. 
Result so far: 978.0
Subtract 344 from 380 to get 36.
Grab the next digit (7) from the dividend, add it to 36, then carry on: 367 / 43

Moving on to step 6:
When dividing 367 by 43, we get 8 with a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 9788.0
If we take 344 away from 367, we end up with 23.
Grab the next digit (7) from the dividend, add it to 23, then carry on: 237 / 43

Advancing to step 7:
237 divided by 43 is 5 with a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 97885.0
If we subtract 215 from 237, we get 22.
Take the next digit (3) from the dividend and append it to 22, then repeat: 223 / 43

Step 8:
43 can be fit into 223 5 times, resulting in a remainder of 8.
The next digit of our result is 5. 
Result so far: 978855.0
The remainder is 8 after subtracting 215 from 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
When dividing 80 by 43, we get 1 with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 978855.1
If we take 43 away from 80, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 10:
43 goes into 370 8 times with a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 978855.18
If we take 344 away from 370, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
When dividing 260 by 43, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 978855.186
Deduct 258 from 260 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
If we divide 20 by 43, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 978855.186
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
200 divided by 43 is 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 978855.18604
Subtract 172 from 200 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 14:
43 goes into 280 6 times with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 978855.186046
Subtracting 258 from 280 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 15:
220 divided by 43 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 978855.1860465
Subtract 215 from 220 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 16:
The number 43 fits into 50 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 978855.18604651
Subtracting 43 from 50 leaves us 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.

After the division, we end up with 978855.18604651 and a remainder of 7e-09.
