64042826 divided by 858 
We're looking to find how many times 858 goes into 64042826.

On to step 1:
6 divided by 858 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 858

Going ahead to step 2:
64 divided by 858 is 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (0) from the dividend, add it to 64, then carry on: 640 / 858

Moving on to step 3:
When dividing 640 by 858, we get 0 with a remainder of 640.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 640, we end up with 640.
Fetch the next digit (4) from the dividend, attach it to 640 and continue: 6404 / 858

Let's proceed to step 4:
When dividing 6404 by 858, we get 7 with a remainder of 398.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 398 after subtracting 6006 from 6404.
Take the next digit (2) from the dividend and append it to 398, then repeat: 3982 / 858

On to step 5:
858 goes into 3982 4 times with a remainder of 550.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
If we subtract 3432 from 3982, we get 550.
Append the next digit (8) from the dividend to 550 and continue with: 5508 / 858

Step 6:
858 goes into 5508 6 times with a remainder of 360.
The number 6 becomes the next digit in our result. 
Result so far: 746.0
Subtracting 5148 from 5508 leaves us with 360.
Include the next digit (2) from the dividend after 360, then repeat: 3602 / 858

Advancing to step 7:
The number 858 fits into 3602 4 times, leaving a remainder of 170.
Use 4 as the next digit of our solution. 
Result so far: 7464.0
The remainder is 170 after subtracting 3432 from 3602.
Take the next digit (6) from the dividend and append it to 170, then repeat: 1706 / 858

Let's proceed to step 8:
When dividing 1706 by 858, we get 1 with a remainder of 848.
Record the quotient 1 as the next digit in the result. 
Result so far: 74641.0
Deduct 858 from 1706 and we're left with 848.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8480, and continue the process.

Going ahead to step 9:
If we divide 8480 by 858, we get 9 and a remainder of 758.
Write down 9 as next digit of the result. 
Result so far: 74641.9
Subtract 7722 from 8480 to get 758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7580, and continue the process.

Going ahead to step 10:
7580 divided by 858 is 8 with a remainder of 716.
The number 8 becomes the next digit in our result. 
Result so far: 74641.98
Subtract 6864 from 7580 to get 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Going ahead to step 11:
When dividing 7160 by 858, we get 8 with a remainder of 296.
Use 8 as the next digit of our solution. 
Result so far: 74641.988
Subtracting 6864 from 7160 leaves us 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.

The final outcome is 74641.988, with a leftover of 0.0296.
