We're dividing 57396415 by 278 
Our goal is to divide 57396415 by 278.

On to step 1:
278 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 278

Step 2:
278 goes into 57 0 times with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Include the next digit (3) from the dividend after 57, then repeat: 573 / 278

Step 3:
278 goes into 573 2 times with a remainder of 17.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 556 from 573 to get 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 278

Moving on to step 4:
When dividing 179 by 278, we get 0 with a remainder of 179.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 179 leaves us with 179.
Append the next digit (6) from the dividend to 179 and continue with: 1796 / 278

Advancing to step 5:
The number 278 fits into 1796 6 times, leaving a remainder of 128.
Write down 6 as next digit of the result. 
Result so far: 206.0
Subtracting 1668 from 1796 leaves us with 128.
Take the next digit (4) from the dividend and append it to 128, then repeat: 1284 / 278

Advancing to step 6:
If we divide 1284 by 278, we get 4 and a remainder of 172.
Use 4 as the next digit of our solution. 
Result so far: 2064.0
Deduct 1112 from 1284 and we're left with 172.
Take the next digit (1) from the dividend and append it to 172, then repeat: 1721 / 278

On to step 7:
When dividing 1721 by 278, we get 6 with a remainder of 53.
Record the quotient 6 as the next digit in the result. 
Result so far: 20646.0
If we subtract 1668 from 1721, we get 53.
Grab the next digit (5) from the dividend, add it to 53, then carry on: 535 / 278

Let's proceed to step 8:
278 goes into 535 1 times with a remainder of 257.
The number 1 becomes the next digit in our result. 
Result so far: 206461.0
The remainder is 257 after subtracting 278 from 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

On to step 9:
278 goes into 2570 9 times with a remainder of 68.
Write down 9 as next digit of the result. 
Result so far: 206461.9
Deduct 2502 from 2570 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 10:
278 goes into 680 2 times with a remainder of 124.
Write down 2 as next digit of the result. 
Result so far: 206461.92
The remainder is 124 after subtracting 556 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 11:
278 goes into 1240 4 times with a remainder of 128.
Record the quotient 4 as the next digit in the result. 
Result so far: 206461.924
The remainder is 128 after subtracting 1112 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 12:
278 goes into 1280 4 times with a remainder of 168.
Put 4 as the next digit of the answer. 
Result so far: 206461.9244
If we subtract 1112 from 1280, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final outcome is 206461.9244, with a leftover of 0.00168.
