We look at the division of 428305 by 31 
Our goal is to divide 428305 by 31.

Let's proceed to step 1:
4 divided by 31 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 31

Advancing to step 2:
The number 31 fits into 42 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 31 from 42 and we're left with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 31

Going ahead to step 3:
118 divided by 31 is 3 with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 93 from 118 to get 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 31

Step 4:
The number 31 fits into 253 8 times, leaving a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 138.0
If we subtract 248 from 253, we get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 31

Step 5:
31 can be fit into 50 1 times, resulting in a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1381.0
If we take 31 away from 50, we end up with 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 31

Advancing to step 6:
If we divide 195 by 31, we get 6 and a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 13816.0
If we subtract 186 from 195, we 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.

Moving on to step 7:
31 goes into 90 2 times with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 13816.2
Deduct 62 from 90 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
If we divide 280 by 31, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 13816.29
Subtracting 279 from 280 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
The number 31 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 13816.29
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
31 can be fit into 100 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 13816.2903
If we subtract 93 from 100, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 11:
70 divided by 31 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 13816.29032
Deduct 62 from 70 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
31 can be fit into 80 2 times, resulting in a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 13816.290322
Deduct 62 from 80 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 13816.290322, and the remainder is 1.8e-06.
