60146486 ÷ 858 
We want to divide 60146486 by 858.

On to step 1:
858 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 858

Let's proceed to step 2:
858 goes into 60 0 times with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 60, we get 60.
Include the next digit (1) from the dividend after 60, then repeat: 601 / 858

Let's proceed to step 3:
The number 858 fits into 601 0 times, leaving a remainder of 601.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 601 after subtracting 0 from 601.
Fetch the next digit (4) from the dividend, attach it to 601 and continue: 6014 / 858

Advancing to step 4:
When dividing 6014 by 858, we get 7 with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 8 after subtracting 6006 from 6014.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 858

Going ahead to step 5:
858 can be fit into 86 0 times, resulting in a remainder of 86.
The next digit of our result is 0. 
Result so far: 70.0
The remainder is 86 after subtracting 0 from 86.
Append the next digit (4) from the dividend to 86 and continue with: 864 / 858

On to step 6:
The number 858 fits into 864 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 701.0
Subtract 858 from 864 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 858

On to step 7:
If we divide 68 by 858, we get 0 and a remainder of 68.
The next digit of our result is 0. 
Result so far: 7010.0
Subtracting 0 from 68 leaves us with 68.
Fetch the next digit (6) from the dividend, attach it to 68 and continue: 686 / 858

On to step 8:
The number 858 fits into 686 0 times, leaving a remainder of 686.
Use 0 as the next digit of our solution. 
Result so far: 70100.0
Deduct 0 from 686 and we're left with 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Let's proceed to step 9:
858 can be fit into 6860 7 times, resulting in a remainder of 854.
Use 7 as the next digit of our solution. 
Result so far: 70100.7
If we take 6006 away from 6860, we end up with 854.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8540, and continue the process.

Advancing to step 10:
8540 divided by 858 is 9 with a remainder of 818.
Write down 9 as next digit of the result. 
Result so far: 70100.79
If we take 7722 away from 8540, we end up with 818.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8180, and continue the process.

Moving on to step 11:
The number 858 fits into 8180 9 times, leaving a remainder of 458.
Record the quotient 9 as the next digit in the result. 
Result so far: 70100.799
Subtracting 7722 from 8180 leaves us with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

After the division, we end up with 70100.799 and a remainder of 0.0458.
