Let's divide 31478402 by 307
Let's see how many times 307 fits into 31478402.

Step 1:
When dividing 3 by 307, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 307

On to step 2:
307 can be fit into 31 0 times, resulting in a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (4) from the dividend, add it to 31, then carry on: 314 / 307

Let's proceed to step 3:
307 goes into 314 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 307 from 314 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 307

Going ahead to step 4:
77 divided by 307 is 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 77, we get 77.
Bring next digit (8) of the dividend behind the 77 and repeat the process: 778 / 307

Advancing to step 5:
307 can be fit into 778 2 times, resulting in a remainder of 164.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Subtracting 614 from 778 leaves us with 164.
Fetch the next digit (4) from the dividend, attach it to 164 and continue: 1644 / 307

Going ahead to step 6:
If we divide 1644 by 307, we get 5 and a remainder of 109.
The next digit of our result is 5. 
Result so far: 1025.0
If we take 1535 away from 1644, we end up with 109.
Grab the next digit (0) from the dividend, add it to 109, then carry on: 1090 / 307

On to step 7:
If we divide 1090 by 307, we get 3 and a remainder of 169.
Put 3 as the next digit of the answer. 
Result so far: 10253.0
Deduct 921 from 1090 and we're left with 169.
Bring next digit (2) of the dividend behind the 169 and repeat the process: 1692 / 307

Moving on to step 8:
307 can be fit into 1692 5 times, resulting in a remainder of 157.
The number 5 becomes the next digit in our result. 
Result so far: 102535.0
Deduct 1535 from 1692 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Advancing to step 9:
307 goes into 1570 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 102535.5
Subtract 1535 from 1570 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
The number 307 fits into 350 1 times, leaving a remainder of 43.
The next digit of our result is 1. 
Result so far: 102535.51
If we take 307 away from 350, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 11:
When dividing 430 by 307, we get 1 with a remainder of 123.
The next digit of our result is 1. 
Result so far: 102535.511
The remainder is 123 after subtracting 307 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

In conclusion, the division gives 102535.511 with a balance of 0.0123.
