98712428 ÷ 278 
We want to figure out the number of times 98712428 can be divided by 278.

On to step 1:
The number 278 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 278

Going ahead to step 2:
The number 278 fits into 98 0 times, leaving a remainder of 98.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 98 and we're left with 98.
Grab the next digit (7) from the dividend, add it to 98, then carry on: 987 / 278

Let's proceed to step 3:
If we divide 987 by 278, we get 3 and a remainder of 153.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 834 from 987 to get 153.
Fetch the next digit (1) from the dividend, attach it to 153 and continue: 1531 / 278

Advancing to step 4:
278 goes into 1531 5 times with a remainder of 141.
The next digit of our result is 5. 
Result so far: 35.0
If we take 1390 away from 1531, we end up with 141.
Include the next digit (2) from the dividend after 141, then repeat: 1412 / 278

Moving on to step 5:
278 can be fit into 1412 5 times, resulting in a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 355.0
If we take 1390 away from 1412, we end up with 22.
Append the next digit (4) from the dividend to 22 and continue with: 224 / 278

Let's proceed to step 6:
278 can be fit into 224 0 times, resulting in a remainder of 224.
Write down 0 as next digit of the result. 
Result so far: 3550.0
Subtract 0 from 224 to get 224.
Take the next digit (2) from the dividend and append it to 224, then repeat: 2242 / 278

Step 7:
2242 divided by 278 is 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 35508.0
The remainder is 18 after subtracting 2224 from 2242.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 278

Advancing to step 8:
188 divided by 278 is 0 with a remainder of 188.
The next digit of our result is 0. 
Result so far: 355080.0
The remainder is 188 after subtracting 0 from 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 9:
The number 278 fits into 1880 6 times, leaving a remainder of 212.
The next digit of our result is 6. 
Result so far: 355080.6
Subtract 1668 from 1880 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 10:
278 can be fit into 2120 7 times, resulting in a remainder of 174.
Use 7 as the next digit of our solution. 
Result so far: 355080.67
Subtract 1946 from 2120 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 11:
When dividing 1740 by 278, we get 6 with a remainder of 72.
The next digit of our result is 6. 
Result so far: 355080.676
The remainder is 72 after subtracting 1668 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 12:
The number 278 fits into 720 2 times, leaving a remainder of 164.
The next digit of our result is 2. 
Result so far: 355080.6762
Subtract 556 from 720 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 13:
1640 divided by 278 is 5 with a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 355080.67625
Deduct 1390 from 1640 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 14:
278 goes into 2500 8 times with a remainder of 276.
Put 8 as the next digit of the answer. 
Result so far: 355080.676258
Subtract 2224 from 2500 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Let's proceed to step 15:
When dividing 2760 by 278, we get 9 with a remainder of 258.
Use 9 as the next digit of our solution. 
Result so far: 355080.6762589
Deduct 2502 from 2760 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 16:
278 goes into 2580 9 times with a remainder of 78.
Record the quotient 9 as the next digit in the result. 
Result so far: 355080.67625899
If we subtract 2502 from 2580, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The final outcome is 355080.67625899, with a leftover of 7.8e-08.
