35404259 divided by 870 
We want to divide 35404259 by 870.

Let's proceed to step 1:
If we divide 3 by 870, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 870

Let's proceed to step 2:
The number 870 fits into 35 0 times, leaving a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Append the next digit (4) from the dividend to 35 and continue with: 354 / 870

Advancing to step 3:
870 can be fit into 354 0 times, resulting in a remainder of 354.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 354, we end up with 354.
Bring next digit (0) of the dividend behind the 354 and repeat the process: 3540 / 870

On to step 4:
870 goes into 3540 4 times with a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 60 after subtracting 3480 from 3540.
Fetch the next digit (4) from the dividend, attach it to 60 and continue: 604 / 870

On to step 5:
604 divided by 870 is 0 with a remainder of 604.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtracting 0 from 604 leaves us with 604.
Append the next digit (2) from the dividend to 604 and continue with: 6042 / 870

Step 6:
870 goes into 6042 6 times with a remainder of 822.
Put 6 as the next digit of the answer. 
Result so far: 406.0
Deduct 5220 from 6042 and we're left with 822.
Include the next digit (5) from the dividend after 822, then repeat: 8225 / 870

Moving on to step 7:
When dividing 8225 by 870, we get 9 with a remainder of 395.
Put 9 as the next digit of the answer. 
Result so far: 4069.0
If we subtract 7830 from 8225, we get 395.
Take the next digit (9) from the dividend and append it to 395, then repeat: 3959 / 870

On to step 8:
3959 divided by 870 is 4 with a remainder of 479.
Write down 4 as next digit of the result. 
Result so far: 40694.0
Subtracting 3480 from 3959 leaves us with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Advancing to step 9:
870 goes into 4790 5 times with a remainder of 440.
Write down 5 as next digit of the result. 
Result so far: 40694.5
Subtracting 4350 from 4790 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 10:
4400 divided by 870 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 40694.55
Subtracting 4350 from 4400 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 40694.55 with a remaining 0.05.
