Let's divide 27871255 by 407
We want to figure out the number of times 27871255 can be divided by 407.

Going ahead to step 1:
407 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 407

Step 2:
27 divided by 407 is 0 with a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 407

Let's proceed to step 3:
The number 407 fits into 278 0 times, leaving a remainder of 278.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 278 after subtracting 0 from 278.
Bring next digit (7) of the dividend behind the 278 and repeat the process: 2787 / 407

Let's proceed to step 4:
If we divide 2787 by 407, we get 6 and a remainder of 345.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 2442 from 2787 and we're left with 345.
Bring next digit (1) of the dividend behind the 345 and repeat the process: 3451 / 407

Moving on to step 5:
407 can be fit into 3451 8 times, resulting in a remainder of 195.
Use 8 as the next digit of our solution. 
Result so far: 68.0
If we take 3256 away from 3451, we end up with 195.
Append the next digit (2) from the dividend to 195 and continue with: 1952 / 407

On to step 6:
1952 divided by 407 is 4 with a remainder of 324.
The next digit of our result is 4. 
Result so far: 684.0
Deduct 1628 from 1952 and we're left with 324.
Include the next digit (5) from the dividend after 324, then repeat: 3245 / 407

Let's proceed to step 7:
The number 407 fits into 3245 7 times, leaving a remainder of 396.
Use 7 as the next digit of our solution. 
Result so far: 6847.0
The remainder is 396 after subtracting 2849 from 3245.
Include the next digit (5) from the dividend after 396, then repeat: 3965 / 407

On to step 8:
When dividing 3965 by 407, we get 9 with a remainder of 302.
Put 9 as the next digit of the answer. 
Result so far: 68479.0
Deduct 3663 from 3965 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Step 9:
The number 407 fits into 3020 7 times, leaving a remainder of 171.
The next digit of our result is 7. 
Result so far: 68479.7
Deduct 2849 from 3020 and we're left with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Advancing to step 10:
If we divide 1710 by 407, we get 4 and a remainder of 82.
Write down 4 as next digit of the result. 
Result so far: 68479.74
If we take 1628 away from 1710, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 11:
The number 407 fits into 820 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 68479.742
Deduct 814 from 820 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
When dividing 60 by 407, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 68479.742
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
407 goes into 600 1 times with a remainder of 193.
Use 1 as the next digit of our solution. 
Result so far: 68479.74201
The remainder is 193 after subtracting 407 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Moving on to step 14:
If we divide 1930 by 407, we get 4 and a remainder of 302.
Record the quotient 4 as the next digit in the result. 
Result so far: 68479.742014
Subtract 1628 from 1930 to get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Going ahead to step 15:
The number 407 fits into 3020 7 times, leaving a remainder of 171.
Write down 7 as next digit of the result. 
Result so far: 68479.7420147
Subtracting 2849 from 3020 leaves us with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Moving on to step 16:
When dividing 1710 by 407, we get 4 with a remainder of 82.
Put 4 as the next digit of the answer. 
Result so far: 68479.74201474
Deduct 1628 from 1710 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

The final outcome is 68479.74201474, with a leftover of 8.2e-08.
