40466570 ÷ 858 
We're looking to find how many times 858 goes into 40466570.

Step 1:
If we divide 4 by 858, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 858

Going ahead to step 2:
858 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
Subtract 0 from 40 to get 40.
Take the next digit (4) from the dividend and append it to 40, then repeat: 404 / 858

Advancing to step 3:
404 divided by 858 is 0 with a remainder of 404.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 404 leaves us with 404.
Include the next digit (6) from the dividend after 404, then repeat: 4046 / 858

Let's proceed to step 4:
If we divide 4046 by 858, we get 4 and a remainder of 614.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 3432 away from 4046, we end up with 614.
Append the next digit (6) from the dividend to 614 and continue with: 6146 / 858

Let's proceed to step 5:
When dividing 6146 by 858, we get 7 with a remainder of 140.
Use 7 as the next digit of our solution. 
Result so far: 47.0
The remainder is 140 after subtracting 6006 from 6146.
Take the next digit (5) from the dividend and append it to 140, then repeat: 1405 / 858

Let's proceed to step 6:
858 can be fit into 1405 1 times, resulting in a remainder of 547.
The next digit of our result is 1. 
Result so far: 471.0
If we subtract 858 from 1405, we get 547.
Grab the next digit (7) from the dividend, add it to 547, then carry on: 5477 / 858

On to step 7:
858 goes into 5477 6 times with a remainder of 329.
Use 6 as the next digit of our solution. 
Result so far: 4716.0
If we subtract 5148 from 5477, we get 329.
Take the next digit (0) from the dividend and append it to 329, then repeat: 3290 / 858

On to step 8:
The number 858 fits into 3290 3 times, leaving a remainder of 716.
The next digit of our result is 3. 
Result so far: 47163.0
Subtracting 2574 from 3290 leaves us with 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Moving on to step 9:
If we divide 7160 by 858, we get 8 and a remainder of 296.
The next digit of our result is 8. 
Result so far: 47163.8
If we take 6864 away from 7160, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 10:
When dividing 2960 by 858, we get 3 with a remainder of 386.
Record the quotient 3 as the next digit in the result. 
Result so far: 47163.83
The remainder is 386 after subtracting 2574 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

On to step 11:
858 goes into 3860 4 times with a remainder of 428.
The number 4 becomes the next digit in our result. 
Result so far: 47163.834
If we take 3432 away from 3860, we end up with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Advancing to step 12:
If we divide 4280 by 858, we get 4 and a remainder of 848.
Put 4 as the next digit of the answer. 
Result so far: 47163.8344
If we subtract 3432 from 4280, we get 848.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8480, and continue the process.

Our division results in 47163.8344 with a remaining 0.00848.
