40260109 divided by 873 
We want to figure out the number of times 40260109 can be divided by 873.

Advancing to step 1:
4 divided by 873 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 873

On to step 2:
873 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Bring next digit (2) of the dividend behind the 40 and repeat the process: 402 / 873

Advancing to step 3:
When dividing 402 by 873, we get 0 with a remainder of 402.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 402 after subtracting 0 from 402.
Fetch the next digit (6) from the dividend, attach it to 402 and continue: 4026 / 873

Advancing to step 4:
873 goes into 4026 4 times with a remainder of 534.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 3492 from 4026 leaves us with 534.
Include the next digit (0) from the dividend after 534, then repeat: 5340 / 873

Moving on to step 5:
When dividing 5340 by 873, we get 6 with a remainder of 102.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we take 5238 away from 5340, we end up with 102.
Grab the next digit (1) from the dividend, add it to 102, then carry on: 1021 / 873

Let's proceed to step 6:
1021 divided by 873 is 1 with a remainder of 148.
The number 1 becomes the next digit in our result. 
Result so far: 461.0
If we subtract 873 from 1021, we get 148.
Fetch the next digit (0) from the dividend, attach it to 148 and continue: 1480 / 873

Moving on to step 7:
1480 divided by 873 is 1 with a remainder of 607.
The next digit of our result is 1. 
Result so far: 4611.0
Deduct 873 from 1480 and we're left with 607.
Append the next digit (9) from the dividend to 607 and continue with: 6079 / 873

On to step 8:
873 goes into 6079 6 times with a remainder of 841.
Record the quotient 6 as the next digit in the result. 
Result so far: 46116.0
Deduct 5238 from 6079 and we're left with 841.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8410, and continue the process.

Going ahead to step 9:
If we divide 8410 by 873, we get 9 and a remainder of 553.
Put 9 as the next digit of the answer. 
Result so far: 46116.9
If we subtract 7857 from 8410, we get 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Let's proceed to step 10:
If we divide 5530 by 873, we get 6 and a remainder of 292.
The next digit of our result is 6. 
Result so far: 46116.96
Subtracting 5238 from 5530 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 11:
873 can be fit into 2920 3 times, resulting in a remainder of 301.
The number 3 becomes the next digit in our result. 
Result so far: 46116.963
Deduct 2619 from 2920 and we're left with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 12:
873 goes into 3010 3 times with a remainder of 391.
The number 3 becomes the next digit in our result. 
Result so far: 46116.9633
If we subtract 2619 from 3010, we get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Our division results in 46116.9633 with a remaining 0.00391.
