We look at the division of 43678814 by 421 
Our goal is to divide 43678814 by 421.

Moving on to step 1:
The number 421 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 421

Let's proceed to step 2:
421 goes into 43 0 times with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Append the next digit (6) from the dividend to 43 and continue with: 436 / 421

On to step 3:
The number 421 fits into 436 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 421 from 436 leaves us with 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 421

Advancing to step 4:
421 goes into 157 0 times with a remainder of 157.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 157, we get 157.
Include the next digit (8) from the dividend after 157, then repeat: 1578 / 421

Let's proceed to step 5:
421 can be fit into 1578 3 times, resulting in a remainder of 315.
Write down 3 as next digit of the result. 
Result so far: 103.0
The remainder is 315 after subtracting 1263 from 1578.
Take the next digit (8) from the dividend and append it to 315, then repeat: 3158 / 421

Let's proceed to step 6:
When dividing 3158 by 421, we get 7 with a remainder of 211.
Use 7 as the next digit of our solution. 
Result so far: 1037.0
If we subtract 2947 from 3158, we get 211.
Append the next digit (1) from the dividend to 211 and continue with: 2111 / 421

On to step 7:
The number 421 fits into 2111 5 times, leaving a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 10375.0
Deduct 2105 from 2111 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 421

Step 8:
The number 421 fits into 64 0 times, leaving a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 103750.0
If we take 0 away from 64, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 9:
421 can be fit into 640 1 times, resulting in a remainder of 219.
Use 1 as the next digit of our solution. 
Result so far: 103750.1
If we subtract 421 from 640, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

On to step 10:
421 goes into 2190 5 times with a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 103750.15
Subtract 2105 from 2190 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 11:
850 divided by 421 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 103750.152
If we subtract 842 from 850, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
When dividing 80 by 421, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 103750.152
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
800 divided by 421 is 1 with a remainder of 379.
Use 1 as the next digit of our solution. 
Result so far: 103750.15201
Subtracting 421 from 800 leaves us with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Moving on to step 14:
When dividing 3790 by 421, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 103750.152019
If we take 3789 away from 3790, we end up with 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 15:
If we divide 10 by 421, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 103750.152019
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 16:
If we divide 100 by 421, we get 0 and a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 103750.152019
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 103750.152019, with a leftover of 1e-07.
