We look at the division of 78070356 by 278 
We're looking to find how many times 278 goes into 78070356.

Step 1:
7 divided by 278 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 278

Step 2:
When dividing 78 by 278, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Append the next digit (0) from the dividend to 78 and continue with: 780 / 278

Let's proceed to step 3:
If we divide 780 by 278, we get 2 and a remainder of 224.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 556 from 780, we get 224.
Take the next digit (7) from the dividend and append it to 224, then repeat: 2247 / 278

Let's proceed to step 4:
When dividing 2247 by 278, we get 8 with a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
The remainder is 23 after subtracting 2224 from 2247.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 278

On to step 5:
278 goes into 230 0 times with a remainder of 230.
Put 0 as the next digit of the answer. 
Result so far: 280.0
Subtracting 0 from 230 leaves us with 230.
Bring next digit (3) of the dividend behind the 230 and repeat the process: 2303 / 278

Moving on to step 6:
278 can be fit into 2303 8 times, resulting in a remainder of 79.
Use 8 as the next digit of our solution. 
Result so far: 2808.0
If we subtract 2224 from 2303, we get 79.
Include the next digit (5) from the dividend after 79, then repeat: 795 / 278

Step 7:
278 goes into 795 2 times with a remainder of 239.
Use 2 as the next digit of our solution. 
Result so far: 28082.0
If we take 556 away from 795, we end up with 239.
Fetch the next digit (6) from the dividend, attach it to 239 and continue: 2396 / 278

Let's proceed to step 8:
If we divide 2396 by 278, we get 8 and a remainder of 172.
Put 8 as the next digit of the answer. 
Result so far: 280828.0
If we subtract 2224 from 2396, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 9:
278 goes into 1720 6 times with a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 280828.6
Subtract 1668 from 1720 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
278 can be fit into 520 1 times, resulting in a remainder of 242.
Write down 1 as next digit of the result. 
Result so far: 280828.61
Subtract 278 from 520 to get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Advancing to step 11:
2420 divided by 278 is 8 with a remainder of 196.
Use 8 as the next digit of our solution. 
Result so far: 280828.618
If we subtract 2224 from 2420, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 12:
The number 278 fits into 1960 7 times, leaving a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 280828.6187
Deduct 1946 from 1960 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 13:
If we divide 140 by 278, we get 0 and a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 280828.6187
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 14:
When dividing 1400 by 278, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 280828.618705
If we take 1390 away from 1400, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 15:
100 divided by 278 is 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 280828.618705
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 16:
1000 divided by 278 is 3 with a remainder of 166.
Put 3 as the next digit of the answer. 
Result so far: 280828.61870503
Subtract 834 from 1000 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

The final result is 280828.61870503 with a remainder of 1.66e-07.
