We're dividing 43121424 by 284 
We want to figure out the number of times 43121424 can be divided by 284.

Advancing to step 1:
284 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 284

Let's proceed to step 2:
43 divided by 284 is 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 284

Let's proceed to step 3:
431 divided by 284 is 1 with a remainder of 147.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 284 from 431 and we're left with 147.
Take the next digit (2) from the dividend and append it to 147, then repeat: 1472 / 284

Going ahead to step 4:
1472 divided by 284 is 5 with a remainder of 52.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 1420 from 1472, we get 52.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 284

Going ahead to step 5:
When dividing 521 by 284, we get 1 with a remainder of 237.
Write down 1 as next digit of the result. 
Result so far: 151.0
Subtracting 284 from 521 leaves us with 237.
Grab the next digit (4) from the dividend, add it to 237, then carry on: 2374 / 284

Going ahead to step 6:
If we divide 2374 by 284, we get 8 and a remainder of 102.
Write down 8 as next digit of the result. 
Result so far: 1518.0
Deduct 2272 from 2374 and we're left with 102.
Take the next digit (2) from the dividend and append it to 102, then repeat: 1022 / 284

Let's proceed to step 7:
1022 divided by 284 is 3 with a remainder of 170.
The next digit of our result is 3. 
Result so far: 15183.0
Subtract 852 from 1022 to get 170.
Grab the next digit (4) from the dividend, add it to 170, then carry on: 1704 / 284

Going ahead to step 8:
284 can be fit into 1704 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 151836.0
Deduct 1704 from 1704 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
If we divide 0 by 284, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 151836.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
The number 284 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 151836.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 151836.0 with a remaining 0.0.
