We look at the division of 87863770 by 417 
We want to figure out the number of times 87863770 can be divided by 417.

Advancing to step 1:
417 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 417

Let's proceed to step 2:
87 divided by 417 is 0 with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Take the next digit (8) from the dividend and append it to 87, then repeat: 878 / 417

Let's proceed to step 3:
The number 417 fits into 878 2 times, leaving a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 834 from 878 to get 44.
Append the next digit (6) from the dividend to 44 and continue with: 446 / 417

Let's proceed to step 4:
The number 417 fits into 446 1 times, leaving a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 417 from 446 to get 29.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 417

On to step 5:
417 goes into 293 0 times with a remainder of 293.
The next digit of our result is 0. 
Result so far: 210.0
If we take 0 away from 293, we end up with 293.
Take the next digit (7) from the dividend and append it to 293, then repeat: 2937 / 417

On to step 6:
417 can be fit into 2937 7 times, resulting in a remainder of 18.
The next digit of our result is 7. 
Result so far: 2107.0
The remainder is 18 after subtracting 2919 from 2937.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 417

Moving on to step 7:
187 divided by 417 is 0 with a remainder of 187.
The next digit of our result is 0. 
Result so far: 21070.0
Deduct 0 from 187 and we're left with 187.
Bring next digit (0) of the dividend behind the 187 and repeat the process: 1870 / 417

Moving on to step 8:
417 goes into 1870 4 times with a remainder of 202.
Put 4 as the next digit of the answer. 
Result so far: 210704.0
If we subtract 1668 from 1870, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 9:
417 goes into 2020 4 times with a remainder of 352.
Put 4 as the next digit of the answer. 
Result so far: 210704.4
Deduct 1668 from 2020 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 10:
The number 417 fits into 3520 8 times, leaving a remainder of 184.
The number 8 becomes the next digit in our result. 
Result so far: 210704.48
Subtract 3336 from 3520 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 11:
If we divide 1840 by 417, we get 4 and a remainder of 172.
The next digit of our result is 4. 
Result so far: 210704.484
Subtracting 1668 from 1840 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 12:
417 can be fit into 1720 4 times, resulting in a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 210704.4844
Deduct 1668 from 1720 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 210704.4844, with a leftover of 0.00052.
