428070 divided by 31 
Let's see how many times 31 fits into 428070.

Going ahead to step 1:
When dividing 4 by 31, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 31

Moving on to step 2:
When dividing 42 by 31, we get 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 31 from 42 and we're left with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 31

Step 3:
118 divided by 31 is 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 93 from 118 leaves us with 25.
Include the next digit (0) from the dividend after 25, then repeat: 250 / 31

Going ahead to step 4:
If we divide 250 by 31, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 138.0
Subtract 248 from 250 to get 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 31

Going ahead to step 5:
The number 31 fits into 27 0 times, leaving a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 1380.0
Subtracting 0 from 27 leaves us with 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 31

Advancing to step 6:
If we divide 270 by 31, we get 8 and a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 13808.0
The remainder is 22 after subtracting 248 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
31 can be fit into 220 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 13808.7
Deduct 217 from 220 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 8:
31 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 13808.7
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
When dividing 300 by 31, we get 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 13808.709
If we subtract 279 from 300, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 10:
31 goes into 210 6 times with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 13808.7096
The remainder is 24 after subtracting 186 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
If we divide 240 by 31, we get 7 and a remainder of 23.
The next digit of our result is 7. 
Result so far: 13808.70967
Subtracting 217 from 240 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 12:
31 can be fit into 230 7 times, resulting in a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 13808.709677
If we subtract 217 from 230, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 13808.709677 with a balance of 1.3e-06.
