We're dividing 60400819 by 858 
Let's see how many times 858 fits into 60400819.

Moving on to step 1:
858 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 858

Moving on to step 2:
858 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 60 leaves us with 60.
Grab the next digit (4) from the dividend, add it to 60, then carry on: 604 / 858

Step 3:
If we divide 604 by 858, we get 0 and a remainder of 604.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 604 and we're left with 604.
Take the next digit (0) from the dividend and append it to 604, then repeat: 6040 / 858

Going ahead to step 4:
The number 858 fits into 6040 7 times, leaving a remainder of 34.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 6006 from 6040 leaves us with 34.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 858

Going ahead to step 5:
858 can be fit into 340 0 times, resulting in a remainder of 340.
Write down 0 as next digit of the result. 
Result so far: 70.0
Subtract 0 from 340 to get 340.
Append the next digit (8) from the dividend to 340 and continue with: 3408 / 858

On to step 6:
858 can be fit into 3408 3 times, resulting in a remainder of 834.
Write down 3 as next digit of the result. 
Result so far: 703.0
If we subtract 2574 from 3408, we get 834.
Take the next digit (1) from the dividend and append it to 834, then repeat: 8341 / 858

Advancing to step 7:
When dividing 8341 by 858, we get 9 with a remainder of 619.
Write down 9 as next digit of the result. 
Result so far: 7039.0
Subtract 7722 from 8341 to get 619.
Include the next digit (9) from the dividend after 619, then repeat: 6199 / 858

Let's proceed to step 8:
6199 divided by 858 is 7 with a remainder of 193.
The next digit of our result is 7. 
Result so far: 70397.0
If we subtract 6006 from 6199, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Step 9:
1930 divided by 858 is 2 with a remainder of 214.
Put 2 as the next digit of the answer. 
Result so far: 70397.2
Deduct 1716 from 1930 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 10:
If we divide 2140 by 858, we get 2 and a remainder of 424.
Put 2 as the next digit of the answer. 
Result so far: 70397.22
The remainder is 424 after subtracting 1716 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

After the division, we end up with 70397.22 and a remainder of 0.424.
