39275449 ÷ 31 
Our goal is to divide 39275449 by 31.

Moving on to step 1:
When dividing 3 by 31, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 31

Going ahead to step 2:
The number 31 fits into 39 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
If we take 31 away from 39, we end up with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 31

Advancing to step 3:
31 can be fit into 82 2 times, resulting in a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 20 after subtracting 62 from 82.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 31

Step 4:
31 can be fit into 207 6 times, resulting in a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 126.0
Deduct 186 from 207 and we're left with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 31

Moving on to step 5:
If we divide 215 by 31, we get 6 and a remainder of 29.
The number 6 becomes the next digit in our result. 
Result so far: 1266.0
Deduct 186 from 215 and we're left with 29.
Include the next digit (4) from the dividend after 29, then repeat: 294 / 31

Advancing to step 6:
The number 31 fits into 294 9 times, leaving a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 12669.0
Deduct 279 from 294 and we're left with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 31

Advancing to step 7:
31 can be fit into 154 4 times, resulting in a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 126694.0
If we take 124 away from 154, we end up with 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 31

Advancing to step 8:
The number 31 fits into 309 9 times, leaving a remainder of 30.
Write down 9 as next digit of the result. 
Result so far: 1266949.0
Subtract 279 from 309 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
The number 31 fits into 300 9 times, leaving a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 1266949.9
Deduct 279 from 300 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 10:
31 can be fit into 210 6 times, resulting in a remainder of 24.
The next digit of our result is 6. 
Result so far: 1266949.96
Subtract 186 from 210 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
31 goes into 240 7 times with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 1266949.967
Subtract 217 from 240 to 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.

Let's proceed to step 12:
31 can be fit into 230 7 times, resulting in a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 1266949.9677
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.

The quotient of the division is 1266949.9677, and the remainder is 0.00013.
