We're dividing 55081688 by 858 
Our goal is to divide 55081688 by 858.

Let's proceed to step 1:
When dividing 5 by 858, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 858

Going ahead to step 2:
The number 858 fits into 55 0 times, leaving a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Fetch the next digit (0) from the dividend, attach it to 55 and continue: 550 / 858

Moving on to step 3:
If we divide 550 by 858, we get 0 and a remainder of 550.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 550 and we're left with 550.
Take the next digit (8) from the dividend and append it to 550, then repeat: 5508 / 858

Going ahead to step 4:
If we divide 5508 by 858, we get 6 and a remainder of 360.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 5148 from 5508 and we're left with 360.
Bring next digit (1) of the dividend behind the 360 and repeat the process: 3601 / 858

Moving on to step 5:
858 goes into 3601 4 times with a remainder of 169.
The next digit of our result is 4. 
Result so far: 64.0
Deduct 3432 from 3601 and we're left with 169.
Fetch the next digit (6) from the dividend, attach it to 169 and continue: 1696 / 858

Step 6:
1696 divided by 858 is 1 with a remainder of 838.
The number 1 becomes the next digit in our result. 
Result so far: 641.0
The remainder is 838 after subtracting 858 from 1696.
Grab the next digit (8) from the dividend, add it to 838, then carry on: 8388 / 858

On to step 7:
When dividing 8388 by 858, we get 9 with a remainder of 666.
Record the quotient 9 as the next digit in the result. 
Result so far: 6419.0
If we take 7722 away from 8388, we end up with 666.
Take the next digit (8) from the dividend and append it to 666, then repeat: 6668 / 858

Advancing to step 8:
If we divide 6668 by 858, we get 7 and a remainder of 662.
Use 7 as the next digit of our solution. 
Result so far: 64197.0
If we subtract 6006 from 6668, we get 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Let's proceed to step 9:
The number 858 fits into 6620 7 times, leaving a remainder of 614.
Write down 7 as next digit of the result. 
Result so far: 64197.7
Subtracting 6006 from 6620 leaves us with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Step 10:
The number 858 fits into 6140 7 times, leaving a remainder of 134.
Put 7 as the next digit of the answer. 
Result so far: 64197.77
Deduct 6006 from 6140 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Our division results in 64197.77 with a remaining 0.134.
