43421163 ÷ 278 
We want to divide 43421163 by 278.

Let's proceed to step 1:
The number 278 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 278

Going ahead to step 2:
278 can be fit into 43 0 times, resulting in a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 278

On to step 3:
434 divided by 278 is 1 with a remainder of 156.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 278 from 434, we get 156.
Bring next digit (2) of the dividend behind the 156 and repeat the process: 1562 / 278

Going ahead to step 4:
The number 278 fits into 1562 5 times, leaving a remainder of 172.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 1390 from 1562, we get 172.
Fetch the next digit (1) from the dividend, attach it to 172 and continue: 1721 / 278

Let's proceed to step 5:
If we divide 1721 by 278, we get 6 and a remainder of 53.
Put 6 as the next digit of the answer. 
Result so far: 156.0
If we take 1668 away from 1721, we end up with 53.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 278

Going ahead to step 6:
If we divide 531 by 278, we get 1 and a remainder of 253.
Put 1 as the next digit of the answer. 
Result so far: 1561.0
Subtract 278 from 531 to get 253.
Fetch the next digit (6) from the dividend, attach it to 253 and continue: 2536 / 278

On to step 7:
The number 278 fits into 2536 9 times, leaving a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 15619.0
If we subtract 2502 from 2536, we get 34.
Bring next digit (3) of the dividend behind the 34 and repeat the process: 343 / 278

On to step 8:
If we divide 343 by 278, we get 1 and a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 156191.0
The remainder is 65 after subtracting 278 from 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 9:
If we divide 650 by 278, we get 2 and a remainder of 94.
The next digit of our result is 2. 
Result so far: 156191.2
Subtract 556 from 650 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 10:
940 divided by 278 is 3 with a remainder of 106.
Use 3 as the next digit of our solution. 
Result so far: 156191.23
Deduct 834 from 940 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 11:
The number 278 fits into 1060 3 times, leaving a remainder of 226.
Record the quotient 3 as the next digit in the result. 
Result so far: 156191.233
If we subtract 834 from 1060, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

The quotient of the division is 156191.233, and the remainder is 0.0226.
