We look at the division of 13947621 by 712 
We're looking to find how many times 712 goes into 13947621.

On to step 1:
If we divide 1 by 712, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 712

Advancing to step 2:
13 divided by 712 is 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 712

On to step 3:
712 goes into 139 0 times with a remainder of 139.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 139, we end up with 139.
Include the next digit (4) from the dividend after 139, then repeat: 1394 / 712

Step 4:
The number 712 fits into 1394 1 times, leaving a remainder of 682.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 712 from 1394, we get 682.
Take the next digit (7) from the dividend and append it to 682, then repeat: 6827 / 712

Step 5:
6827 divided by 712 is 9 with a remainder of 419.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 6408 from 6827 leaves us with 419.
Bring next digit (6) of the dividend behind the 419 and repeat the process: 4196 / 712

Step 6:
712 can be fit into 4196 5 times, resulting in a remainder of 636.
The next digit of our result is 5. 
Result so far: 195.0
Deduct 3560 from 4196 and we're left with 636.
Grab the next digit (2) from the dividend, add it to 636, then carry on: 6362 / 712

Going ahead to step 7:
The number 712 fits into 6362 8 times, leaving a remainder of 666.
Record the quotient 8 as the next digit in the result. 
Result so far: 1958.0
If we subtract 5696 from 6362, we get 666.
Bring next digit (1) of the dividend behind the 666 and repeat the process: 6661 / 712

On to step 8:
When dividing 6661 by 712, we get 9 with a remainder of 253.
Write down 9 as next digit of the result. 
Result so far: 19589.0
If we take 6408 away from 6661, we end up with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Moving on to step 9:
2530 divided by 712 is 3 with a remainder of 394.
Use 3 as the next digit of our solution. 
Result so far: 19589.3
Deduct 2136 from 2530 and we're left with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Going ahead to step 10:
If we divide 3940 by 712, we get 5 and a remainder of 380.
Put 5 as the next digit of the answer. 
Result so far: 19589.35
Subtract 3560 from 3940 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 11:
If we divide 3800 by 712, we get 5 and a remainder of 240.
The next digit of our result is 5. 
Result so far: 19589.355
The remainder is 240 after subtracting 3560 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 19589.355 with a remainder of 0.024.
