40850177 ÷ 858 
We want to figure out the number of times 40850177 can be divided by 858.

On to step 1:
4 divided by 858 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 858

Moving on to step 2:
40 divided by 858 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 858

On to step 3:
If we divide 408 by 858, we get 0 and a remainder of 408.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 408 leaves us with 408.
Include the next digit (5) from the dividend after 408, then repeat: 4085 / 858

On to step 4:
858 can be fit into 4085 4 times, resulting in a remainder of 653.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 3432 from 4085 and we're left with 653.
Fetch the next digit (0) from the dividend, attach it to 653 and continue: 6530 / 858

Advancing to step 5:
The number 858 fits into 6530 7 times, leaving a remainder of 524.
The next digit of our result is 7. 
Result so far: 47.0
Deduct 6006 from 6530 and we're left with 524.
Bring next digit (1) of the dividend behind the 524 and repeat the process: 5241 / 858

On to step 6:
The number 858 fits into 5241 6 times, leaving a remainder of 93.
The next digit of our result is 6. 
Result so far: 476.0
Subtracting 5148 from 5241 leaves us with 93.
Grab the next digit (7) from the dividend, add it to 93, then carry on: 937 / 858

Let's proceed to step 7:
858 can be fit into 937 1 times, resulting in a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 4761.0
The remainder is 79 after subtracting 858 from 937.
Fetch the next digit (7) from the dividend, attach it to 79 and continue: 797 / 858

On to step 8:
The number 858 fits into 797 0 times, leaving a remainder of 797.
Use 0 as the next digit of our solution. 
Result so far: 47610.0
Subtract 0 from 797 to get 797.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7970, and continue the process.

On to step 9:
The number 858 fits into 7970 9 times, leaving a remainder of 248.
Write down 9 as next digit of the result. 
Result so far: 47610.9
Deduct 7722 from 7970 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 10:
When dividing 2480 by 858, we get 2 with a remainder of 764.
The number 2 becomes the next digit in our result. 
Result so far: 47610.92
If we take 1716 away from 2480, we end up with 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Let's proceed to step 11:
7640 divided by 858 is 8 with a remainder of 776.
The number 8 becomes the next digit in our result. 
Result so far: 47610.928
Deduct 6864 from 7640 and we're left with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Let's proceed to step 12:
When dividing 7760 by 858, we get 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 47610.9289
Subtracting 7722 from 7760 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 13:
The number 858 fits into 380 0 times, leaving a remainder of 380.
Write down 0 as next digit of the result. 
Result so far: 47610.9289
Subtract 0 from 380 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 14:
858 can be fit into 3800 4 times, resulting in a remainder of 368.
The number 4 becomes the next digit in our result. 
Result so far: 47610.928904
The remainder is 368 after subtracting 3432 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 15:
3680 divided by 858 is 4 with a remainder of 248.
Put 4 as the next digit of the answer. 
Result so far: 47610.9289044
Subtracting 3432 from 3680 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

After the division, we end up with 47610.9289044 and a remainder of 2.48e-06.
