3972606 divided by 868 
We're looking to find how many times 868 goes into 3972606.

Moving on to step 1:
When dividing 3 by 868, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 868

Moving on to step 2:
The number 868 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Take the next digit (7) from the dividend and append it to 39, then repeat: 397 / 868

Let's proceed to step 3:
868 goes into 397 0 times with a remainder of 397.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 397 after subtracting 0 from 397.
Include the next digit (2) from the dividend after 397, then repeat: 3972 / 868

Let's proceed to step 4:
3972 divided by 868 is 4 with a remainder of 500.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 3472 from 3972, we get 500.
Fetch the next digit (6) from the dividend, attach it to 500 and continue: 5006 / 868

Going ahead to step 5:
5006 divided by 868 is 5 with a remainder of 666.
Write down 5 as next digit of the result. 
Result so far: 45.0
Subtract 4340 from 5006 to get 666.
Fetch the next digit (0) from the dividend, attach it to 666 and continue: 6660 / 868

Moving on to step 6:
868 can be fit into 6660 7 times, resulting in a remainder of 584.
The number 7 becomes the next digit in our result. 
Result so far: 457.0
Deduct 6076 from 6660 and we're left with 584.
Take the next digit (6) from the dividend and append it to 584, then repeat: 5846 / 868

Going ahead to step 7:
5846 divided by 868 is 6 with a remainder of 638.
Put 6 as the next digit of the answer. 
Result so far: 4576.0
If we take 5208 away from 5846, we end up with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Advancing to step 8:
868 goes into 6380 7 times with a remainder of 304.
Write down 7 as next digit of the result. 
Result so far: 4576.7
If we take 6076 away from 6380, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 9:
3040 divided by 868 is 3 with a remainder of 436.
Put 3 as the next digit of the answer. 
Result so far: 4576.73
If we take 2604 away from 3040, we end up with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Let's proceed to step 10:
4360 divided by 868 is 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 4576.735
If we take 4340 away from 4360, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
868 goes into 200 0 times with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 4576.735
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 12:
868 can be fit into 2000 2 times, resulting in a remainder of 264.
The next digit of our result is 2. 
Result so far: 4576.73502
Deduct 1736 from 2000 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 13:
If we divide 2640 by 868, we get 3 and a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 4576.735023
Deduct 2604 from 2640 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
360 divided by 868 is 0 with a remainder of 360.
The next digit of our result is 0. 
Result so far: 4576.735023
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 15:
The number 868 fits into 3600 4 times, leaving a remainder of 128.
The next digit of our result is 4. 
Result so far: 4576.73502304
Subtract 3472 from 3600 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final result is 4576.73502304 with a remainder of 1.28e-07.
