We look at the division of 80406 by 57 
Let's see how many times 57 fits into 80406.

On to step 1:
8 divided by 57 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 57

Step 2:
When dividing 80 by 57, we get 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 1.0
If we take 57 away from 80, we end up with 23.
Take the next digit (4) from the dividend and append it to 23, then repeat: 234 / 57

Let's proceed to step 3:
If we divide 234 by 57, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 228 from 234, we get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 57

Going ahead to step 4:
If we divide 60 by 57, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 141.0
If we subtract 57 from 60, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 57

Let's proceed to step 5:
The number 57 fits into 36 0 times, leaving a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 1410.0
Subtract 0 from 36 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 6:
When dividing 360 by 57, we get 6 with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 1410.6
If we subtract 342 from 360, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
57 goes into 180 3 times with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 1410.63
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 8:
If we divide 90 by 57, we get 1 and a remainder of 33.
The next digit of our result is 1. 
Result so far: 1410.631
If we subtract 57 from 90, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 9:
57 goes into 330 5 times with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 1410.6315
Subtracting 285 from 330 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 10:
If we divide 450 by 57, we get 7 and a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 1410.63157
Deduct 399 from 450 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 11:
57 goes into 510 8 times with a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 1410.631578
Deduct 456 from 510 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 12:
If we divide 540 by 57, we get 9 and a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 1410.6315789
The remainder is 27 after subtracting 513 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 13:
If we divide 270 by 57, we get 4 and a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 1410.63157894
Deduct 228 from 270 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 1410.63157894, with a leftover of 4.2e-08.
