13908488 ÷ 581 
We want to divide 13908488 by 581.

Let's proceed to step 1:
The number 581 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 581

On to step 2:
The number 581 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 581

Step 3:
The number 581 fits into 139 0 times, leaving a remainder of 139.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 139 and we're left with 139.
Grab the next digit (0) from the dividend, add it to 139, then carry on: 1390 / 581

Going ahead to step 4:
When dividing 1390 by 581, we get 2 with a remainder of 228.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 228 after subtracting 1162 from 1390.
Fetch the next digit (8) from the dividend, attach it to 228 and continue: 2288 / 581

Advancing to step 5:
581 goes into 2288 3 times with a remainder of 545.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtract 1743 from 2288 to get 545.
Include the next digit (4) from the dividend after 545, then repeat: 5454 / 581

Going ahead to step 6:
581 goes into 5454 9 times with a remainder of 225.
Use 9 as the next digit of our solution. 
Result so far: 239.0
If we take 5229 away from 5454, we end up with 225.
Fetch the next digit (8) from the dividend, attach it to 225 and continue: 2258 / 581

On to step 7:
2258 divided by 581 is 3 with a remainder of 515.
Put 3 as the next digit of the answer. 
Result so far: 2393.0
Deduct 1743 from 2258 and we're left with 515.
Fetch the next digit (8) from the dividend, attach it to 515 and continue: 5158 / 581

Going ahead to step 8:
When dividing 5158 by 581, we get 8 with a remainder of 510.
Write down 8 as next digit of the result. 
Result so far: 23938.0
The remainder is 510 after subtracting 4648 from 5158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

On to step 9:
The number 581 fits into 5100 8 times, leaving a remainder of 452.
The number 8 becomes the next digit in our result. 
Result so far: 23938.8
If we subtract 4648 from 5100, we get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

On to step 10:
If we divide 4520 by 581, we get 7 and a remainder of 453.
Write down 7 as next digit of the result. 
Result so far: 23938.87
Subtracting 4067 from 4520 leaves us with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Going ahead to step 11:
The number 581 fits into 4530 7 times, leaving a remainder of 463.
Use 7 as the next digit of our solution. 
Result so far: 23938.877
Subtracting 4067 from 4530 leaves us with 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

After the division, we end up with 23938.877 and a remainder of 0.0463.
