We're dividing 13890660 by 572 
We want to figure out the number of times 13890660 can be divided by 572.

Advancing to step 1:
If we divide 1 by 572, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 572

Advancing to step 2:
572 can be fit into 13 0 times, resulting in a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 572

Step 3:
If we divide 138 by 572, we get 0 and a remainder of 138.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 138 and we're left with 138.
Include the next digit (9) from the dividend after 138, then repeat: 1389 / 572

Step 4:
If we divide 1389 by 572, we get 2 and a remainder of 245.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1144 from 1389 to get 245.
Include the next digit (0) from the dividend after 245, then repeat: 2450 / 572

Step 5:
The number 572 fits into 2450 4 times, leaving a remainder of 162.
The next digit of our result is 4. 
Result so far: 24.0
Subtract 2288 from 2450 to get 162.
Include the next digit (6) from the dividend after 162, then repeat: 1626 / 572

Going ahead to step 6:
When dividing 1626 by 572, we get 2 with a remainder of 482.
Write down 2 as next digit of the result. 
Result so far: 242.0
If we take 1144 away from 1626, we end up with 482.
Take the next digit (6) from the dividend and append it to 482, then repeat: 4826 / 572

Advancing to step 7:
The number 572 fits into 4826 8 times, leaving a remainder of 250.
The number 8 becomes the next digit in our result. 
Result so far: 2428.0
If we take 4576 away from 4826, we end up with 250.
Append the next digit (0) from the dividend to 250 and continue with: 2500 / 572

On to step 8:
572 can be fit into 2500 4 times, resulting in a remainder of 212.
Put 4 as the next digit of the answer. 
Result so far: 24284.0
Subtracting 2288 from 2500 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 9:
If we divide 2120 by 572, we get 3 and a remainder of 404.
Record the quotient 3 as the next digit in the result. 
Result so far: 24284.3
If we take 1716 away from 2120, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Step 10:
If we divide 4040 by 572, we get 7 and a remainder of 36.
The next digit of our result is 7. 
Result so far: 24284.37
If we take 4004 away from 4040, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
If we divide 360 by 572, we get 0 and a remainder of 360.
Write down 0 as next digit of the result. 
Result so far: 24284.37
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 12:
If we divide 3600 by 572, we get 6 and a remainder of 168.
Use 6 as the next digit of our solution. 
Result so far: 24284.3706
If we subtract 3432 from 3600, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 13:
If we divide 1680 by 572, we get 2 and a remainder of 536.
Write down 2 as next digit of the result. 
Result so far: 24284.37062
The remainder is 536 after subtracting 1144 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Going ahead to step 14:
If we divide 5360 by 572, we get 9 and a remainder of 212.
The next digit of our result is 9. 
Result so far: 24284.370629
If we take 5148 away from 5360, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 15:
572 can be fit into 2120 3 times, resulting in a remainder of 404.
The next digit of our result is 3. 
Result so far: 24284.3706293
If we take 1716 away from 2120, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 16:
572 goes into 4040 7 times with a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 24284.37062937
Subtract 4004 from 4040 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 24284.37062937 with a balance of 3.6e-08.
