83543485 ÷ 278 
We want to divide 83543485 by 278.

Going ahead to step 1:
278 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 278

Advancing to step 2:
When dividing 83 by 278, we get 0 with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Include the next digit (5) from the dividend after 83, then repeat: 835 / 278

Advancing to step 3:
The number 278 fits into 835 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 834 from 835, we get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 278

Let's proceed to step 4:
278 can be fit into 14 0 times, resulting in a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
The remainder is 14 after subtracting 0 from 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 278

Going ahead to step 5:
When dividing 143 by 278, we get 0 with a remainder of 143.
Use 0 as the next digit of our solution. 
Result so far: 300.0
The remainder is 143 after subtracting 0 from 143.
Bring next digit (4) of the dividend behind the 143 and repeat the process: 1434 / 278

Going ahead to step 6:
The number 278 fits into 1434 5 times, leaving a remainder of 44.
Put 5 as the next digit of the answer. 
Result so far: 3005.0
If we subtract 1390 from 1434, we get 44.
Grab the next digit (8) from the dividend, add it to 44, then carry on: 448 / 278

Advancing to step 7:
278 can be fit into 448 1 times, resulting in a remainder of 170.
Record the quotient 1 as the next digit in the result. 
Result so far: 30051.0
Subtract 278 from 448 to get 170.
Fetch the next digit (5) from the dividend, attach it to 170 and continue: 1705 / 278

Let's proceed to step 8:
278 can be fit into 1705 6 times, resulting in a remainder of 37.
The next digit of our result is 6. 
Result so far: 300516.0
If we take 1668 away from 1705, 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 9:
The number 278 fits into 370 1 times, leaving a remainder of 92.
The next digit of our result is 1. 
Result so far: 300516.1
Deduct 278 from 370 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 10:
920 divided by 278 is 3 with a remainder of 86.
Use 3 as the next digit of our solution. 
Result so far: 300516.13
Subtracting 834 from 920 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 11:
860 divided by 278 is 3 with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 300516.133
Subtract 834 from 860 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 300516.133 and a remainder of 0.0026.
