Let's divide 3987715 by 873
We want to figure out the number of times 3987715 can be divided by 873.

Step 1:
When dividing 3 by 873, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 873

Let's proceed to step 2:
873 goes into 39 0 times with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 873

On to step 3:
873 goes into 398 0 times with a remainder of 398.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 398, we get 398.
Grab the next digit (7) from the dividend, add it to 398, then carry on: 3987 / 873

Step 4:
873 goes into 3987 4 times with a remainder of 495.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 3492 from 3987, we get 495.
Bring next digit (7) of the dividend behind the 495 and repeat the process: 4957 / 873

Going ahead to step 5:
When dividing 4957 by 873, we get 5 with a remainder of 592.
The next digit of our result is 5. 
Result so far: 45.0
Subtract 4365 from 4957 to get 592.
Take the next digit (1) from the dividend and append it to 592, then repeat: 5921 / 873

Advancing to step 6:
873 goes into 5921 6 times with a remainder of 683.
Put 6 as the next digit of the answer. 
Result so far: 456.0
Deduct 5238 from 5921 and we're left with 683.
Fetch the next digit (5) from the dividend, attach it to 683 and continue: 6835 / 873

Let's proceed to step 7:
If we divide 6835 by 873, we get 7 and a remainder of 724.
Record the quotient 7 as the next digit in the result. 
Result so far: 4567.0
Subtracting 6111 from 6835 leaves us with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Let's proceed to step 8:
When dividing 7240 by 873, we get 8 with a remainder of 256.
The next digit of our result is 8. 
Result so far: 4567.8
If we take 6984 away from 7240, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 9:
873 goes into 2560 2 times with a remainder of 814.
Put 2 as the next digit of the answer. 
Result so far: 4567.82
The remainder is 814 after subtracting 1746 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8140, and continue the process.

Let's proceed to step 10:
When dividing 8140 by 873, we get 9 with a remainder of 283.
The next digit of our result is 9. 
Result so far: 4567.829
If we take 7857 away from 8140, we end up with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Advancing to step 11:
When dividing 2830 by 873, we get 3 with a remainder of 211.
Write down 3 as next digit of the result. 
Result so far: 4567.8293
Deduct 2619 from 2830 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Going ahead to step 12:
2110 divided by 873 is 2 with a remainder of 364.
Record the quotient 2 as the next digit in the result. 
Result so far: 4567.82932
Subtract 1746 from 2110 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 13:
If we divide 3640 by 873, we get 4 and a remainder of 148.
Write down 4 as next digit of the result. 
Result so far: 4567.829324
If we subtract 3492 from 3640, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 14:
1480 divided by 873 is 1 with a remainder of 607.
The next digit of our result is 1. 
Result so far: 4567.8293241
Deduct 873 from 1480 and we're left with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Let's proceed to step 15:
873 can be fit into 6070 6 times, resulting in a remainder of 832.
The next digit of our result is 6. 
Result so far: 4567.82932416
If we subtract 5238 from 6070, we get 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

The final outcome is 4567.82932416, with a leftover of 8.32e-07.
