We look at the division of 123445 by 31 
Our goal is to divide 123445 by 31.

Going ahead to step 1:
When dividing 1 by 31, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 31

Let's proceed to step 2:
If we divide 12 by 31, we get 0 and a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 31

Moving on to step 3:
31 can be fit into 123 3 times, resulting in a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 93 from 123, we get 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 31

Moving on to step 4:
If we divide 304 by 31, we get 9 and a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Subtract 279 from 304 to get 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 31

Step 5:
The number 31 fits into 254 8 times, leaving a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 398.0
If we subtract 248 from 254, we get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 31

Going ahead to step 6:
The number 31 fits into 65 2 times, leaving a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 3982.0
If we subtract 62 from 65, we get 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 7:
31 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 3982.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
300 divided by 31 is 9 with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 3982.09
The remainder is 21 after subtracting 279 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 9:
When dividing 210 by 31, we get 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 3982.096
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.

Moving on to step 10:
240 divided by 31 is 7 with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 3982.0967
If we subtract 217 from 240, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 11:
230 divided by 31 is 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 3982.09677
If we take 217 away from 230, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 3982.09677 and a remainder of 1.3e-05.
