Let's divide 43867243 by 438
We want to divide 43867243 by 438.

Advancing to step 1:
When dividing 4 by 438, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 438

On to step 2:
438 goes into 43 0 times with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 438

On to step 3:
438 can be fit into 438 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 438 from 438 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 438

Advancing to step 4:
The number 438 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 438

Step 5:
438 can be fit into 67 0 times, resulting in a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 100.0
Subtract 0 from 67 to get 67.
Fetch the next digit (2) from the dividend, attach it to 67 and continue: 672 / 438

On to step 6:
If we divide 672 by 438, we get 1 and a remainder of 234.
Record the quotient 1 as the next digit in the result. 
Result so far: 1001.0
If we subtract 438 from 672, we get 234.
Append the next digit (4) from the dividend to 234 and continue with: 2344 / 438

Step 7:
When dividing 2344 by 438, we get 5 with a remainder of 154.
Write down 5 as next digit of the result. 
Result so far: 10015.0
Deduct 2190 from 2344 and we're left with 154.
Append the next digit (3) from the dividend to 154 and continue with: 1543 / 438

Step 8:
438 can be fit into 1543 3 times, resulting in a remainder of 229.
Record the quotient 3 as the next digit in the result. 
Result so far: 100153.0
If we subtract 1314 from 1543, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Step 9:
438 can be fit into 2290 5 times, resulting in a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 100153.5
The remainder is 100 after subtracting 2190 from 2290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 10:
1000 divided by 438 is 2 with a remainder of 124.
Record the quotient 2 as the next digit in the result. 
Result so far: 100153.52
If we take 876 away from 1000, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 11:
438 can be fit into 1240 2 times, resulting in a remainder of 364.
Record the quotient 2 as the next digit in the result. 
Result so far: 100153.522
If we take 876 away from 1240, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

After the division, we end up with 100153.522 and a remainder of 0.0364.
