Let's divide 40184661 by 870
We want to divide 40184661 by 870.

On to step 1:
When dividing 4 by 870, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 870

Step 2:
870 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 870

Let's proceed to step 3:
870 can be fit into 401 0 times, resulting in a remainder of 401.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 401 leaves us with 401.
Bring next digit (8) of the dividend behind the 401 and repeat the process: 4018 / 870

Moving on to step 4:
4018 divided by 870 is 4 with a remainder of 538.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 3480 from 4018 to get 538.
Include the next digit (4) from the dividend after 538, then repeat: 5384 / 870

Let's proceed to step 5:
870 can be fit into 5384 6 times, resulting in a remainder of 164.
Use 6 as the next digit of our solution. 
Result so far: 46.0
If we subtract 5220 from 5384, we get 164.
Append the next digit (6) from the dividend to 164 and continue with: 1646 / 870

Moving on to step 6:
If we divide 1646 by 870, we get 1 and a remainder of 776.
The next digit of our result is 1. 
Result so far: 461.0
Deduct 870 from 1646 and we're left with 776.
Take the next digit (6) from the dividend and append it to 776, then repeat: 7766 / 870

Going ahead to step 7:
The number 870 fits into 7766 8 times, leaving a remainder of 806.
The next digit of our result is 8. 
Result so far: 4618.0
Subtract 6960 from 7766 to get 806.
Include the next digit (1) from the dividend after 806, then repeat: 8061 / 870

Going ahead to step 8:
When dividing 8061 by 870, we get 9 with a remainder of 231.
Write down 9 as next digit of the result. 
Result so far: 46189.0
Subtracting 7830 from 8061 leaves us with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Advancing to step 9:
870 can be fit into 2310 2 times, resulting in a remainder of 570.
The number 2 becomes the next digit in our result. 
Result so far: 46189.2
The remainder is 570 after subtracting 1740 from 2310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Going ahead to step 10:
870 goes into 5700 6 times with a remainder of 480.
The number 6 becomes the next digit in our result. 
Result so far: 46189.26
Deduct 5220 from 5700 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 11:
4800 divided by 870 is 5 with a remainder of 450.
Record the quotient 5 as the next digit in the result. 
Result so far: 46189.265
Deduct 4350 from 4800 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 12:
4500 divided by 870 is 5 with a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 46189.2655
Deduct 4350 from 4500 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The final outcome is 46189.2655, with a leftover of 0.0015.
