We divide 31307800 by 280
Our goal is to divide 31307800 by 280.

On to step 1:
280 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 280

Step 2:
When dividing 31 by 280, we get 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 280

Let's proceed to step 3:
The number 280 fits into 313 1 times, leaving a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 280 from 313 leaves us with 33.
Append the next digit (0) from the dividend to 33 and continue with: 330 / 280

Advancing to step 4:
280 can be fit into 330 1 times, resulting in a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 280 from 330 and we're left with 50.
Bring next digit (7) of the dividend behind the 50 and repeat the process: 507 / 280

Step 5:
280 goes into 507 1 times with a remainder of 227.
The number 1 becomes the next digit in our result. 
Result so far: 111.0
The remainder is 227 after subtracting 280 from 507.
Fetch the next digit (8) from the dividend, attach it to 227 and continue: 2278 / 280

Going ahead to step 6:
2278 divided by 280 is 8 with a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 1118.0
Subtracting 2240 from 2278 leaves us with 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 280

Going ahead to step 7:
380 divided by 280 is 1 with a remainder of 100.
Write down 1 as next digit of the result. 
Result so far: 11181.0
Deduct 280 from 380 and we're left with 100.
Fetch the next digit (0) from the dividend, attach it to 100 and continue: 1000 / 280

Moving on to step 8:
The number 280 fits into 1000 3 times, leaving a remainder of 160.
Put 3 as the next digit of the answer. 
Result so far: 111813.0
Deduct 840 from 1000 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 9:
The number 280 fits into 1600 5 times, leaving a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 111813.5
If we subtract 1400 from 1600, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 10:
2000 divided by 280 is 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 111813.57
Subtract 1960 from 2000 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
When dividing 400 by 280, we get 1 with a remainder of 120.
The next digit of our result is 1. 
Result so far: 111813.571
Subtract 280 from 400 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 12:
When dividing 1200 by 280, we get 4 with a remainder of 80.
The next digit of our result is 4. 
Result so far: 111813.5714
If we take 1120 away from 1200, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 13:
280 can be fit into 800 2 times, resulting in a remainder of 240.
The next digit of our result is 2. 
Result so far: 111813.57142
If we take 560 away from 800, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 14:
280 can be fit into 2400 8 times, resulting in a remainder of 160.
Record the quotient 8 as the next digit in the result. 
Result so far: 111813.571428
If we take 2240 away from 2400, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 15:
280 can be fit into 1600 5 times, resulting in a remainder of 200.
The next digit of our result is 5. 
Result so far: 111813.5714285
Subtracting 1400 from 1600 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 16:
The number 280 fits into 2000 7 times, leaving a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 111813.57142857
If we take 1960 away from 2000, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 111813.57142857 with a remainder of 4e-08.
