We look at the division of 99721575 by 278 
We want to figure out the number of times 99721575 can be divided by 278.

Let's proceed to step 1:
278 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 278

On to step 2:
278 can be fit into 99 0 times, resulting in a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Take the next digit (7) from the dividend and append it to 99, then repeat: 997 / 278

Advancing to step 3:
997 divided by 278 is 3 with a remainder of 163.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 163 after subtracting 834 from 997.
Grab the next digit (2) from the dividend, add it to 163, then carry on: 1632 / 278

Going ahead to step 4:
278 can be fit into 1632 5 times, resulting in a remainder of 242.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
The remainder is 242 after subtracting 1390 from 1632.
Take the next digit (1) from the dividend and append it to 242, then repeat: 2421 / 278

Going ahead to step 5:
278 can be fit into 2421 8 times, resulting in a remainder of 197.
Write down 8 as next digit of the result. 
Result so far: 358.0
If we take 2224 away from 2421, we end up with 197.
Grab the next digit (5) from the dividend, add it to 197, then carry on: 1975 / 278

Step 6:
The number 278 fits into 1975 7 times, leaving a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 3587.0
If we subtract 1946 from 1975, we get 29.
Bring next digit (7) of the dividend behind the 29 and repeat the process: 297 / 278

Moving on to step 7:
278 goes into 297 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 35871.0
Deduct 278 from 297 and we're left with 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 278

Let's proceed to step 8:
278 goes into 195 0 times with a remainder of 195.
The number 0 becomes the next digit in our result. 
Result so far: 358710.0
Deduct 0 from 195 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 9:
278 goes into 1950 7 times with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 358710.7
Subtract 1946 from 1950 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
278 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 358710.7
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
The number 278 fits into 400 1 times, leaving a remainder of 122.
The number 1 becomes the next digit in our result. 
Result so far: 358710.701
If we subtract 278 from 400, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 12:
1220 divided by 278 is 4 with a remainder of 108.
Record the quotient 4 as the next digit in the result. 
Result so far: 358710.7014
If we subtract 1112 from 1220, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 13:
1080 divided by 278 is 3 with a remainder of 246.
The next digit of our result is 3. 
Result so far: 358710.70143
Deduct 834 from 1080 and we're left with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 14:
If we divide 2460 by 278, we get 8 and a remainder of 236.
The number 8 becomes the next digit in our result. 
Result so far: 358710.701438
The remainder is 236 after subtracting 2224 from 2460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 15:
If we divide 2360 by 278, we get 8 and a remainder of 136.
Put 8 as the next digit of the answer. 
Result so far: 358710.7014388
Subtracting 2224 from 2360 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

After the division, we end up with 358710.7014388 and a remainder of 1.36e-06.
