We look at the division of 57373139 by 806 
Let's see how many times 806 fits into 57373139.

Going ahead to step 1:
806 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 806

On to step 2:
806 goes into 57 0 times with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Bring next digit (3) of the dividend behind the 57 and repeat the process: 573 / 806

Advancing to step 3:
806 goes into 573 0 times with a remainder of 573.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 573, we get 573.
Bring next digit (7) of the dividend behind the 573 and repeat the process: 5737 / 806

Let's proceed to step 4:
If we divide 5737 by 806, we get 7 and a remainder of 95.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 5642 from 5737 and we're left with 95.
Grab the next digit (3) from the dividend, add it to 95, then carry on: 953 / 806

Going ahead to step 5:
953 divided by 806 is 1 with a remainder of 147.
The next digit of our result is 1. 
Result so far: 71.0
The remainder is 147 after subtracting 806 from 953.
Grab the next digit (1) from the dividend, add it to 147, then carry on: 1471 / 806

Going ahead to step 6:
The number 806 fits into 1471 1 times, leaving a remainder of 665.
The next digit of our result is 1. 
Result so far: 711.0
Subtracting 806 from 1471 leaves us with 665.
Fetch the next digit (3) from the dividend, attach it to 665 and continue: 6653 / 806

Step 7:
The number 806 fits into 6653 8 times, leaving a remainder of 205.
Write down 8 as next digit of the result. 
Result so far: 7118.0
If we subtract 6448 from 6653, we get 205.
Append the next digit (9) from the dividend to 205 and continue with: 2059 / 806

Moving on to step 8:
2059 divided by 806 is 2 with a remainder of 447.
Write down 2 as next digit of the result. 
Result so far: 71182.0
If we subtract 1612 from 2059, we get 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

On to step 9:
4470 divided by 806 is 5 with a remainder of 440.
Write down 5 as next digit of the result. 
Result so far: 71182.5
Subtract 4030 from 4470 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 10:
If we divide 4400 by 806, we get 5 and a remainder of 370.
Record the quotient 5 as the next digit in the result. 
Result so far: 71182.55
Deduct 4030 from 4400 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Our division results in 71182.55 with a remaining 0.37.
