We look at the division of 12205478 by 71 
We want to figure out the number of times 12205478 can be divided by 71.

Advancing to step 1:
The number 71 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 71

Let's proceed to step 2:
If we divide 12 by 71, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 71

Moving on to step 3:
71 can be fit into 122 1 times, resulting in a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 71 away from 122, we end up with 51.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 71

On to step 4:
If we divide 510 by 71, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 497 from 510 to get 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 71

Advancing to step 5:
71 goes into 135 1 times with a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 171.0
Deduct 71 from 135 and we're left with 64.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 71

Advancing to step 6:
71 can be fit into 644 9 times, resulting in a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 1719.0
Subtracting 639 from 644 leaves us with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 71

Let's proceed to step 7:
If we divide 57 by 71, we get 0 and a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 17190.0
If we subtract 0 from 57, we get 57.
Take the next digit (8) from the dividend and append it to 57, then repeat: 578 / 71

Let's proceed to step 8:
The number 71 fits into 578 8 times, leaving a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 171908.0
Subtract 568 from 578 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
The number 71 fits into 100 1 times, leaving a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 171908.1
If we subtract 71 from 100, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 10:
When dividing 290 by 71, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 171908.14
The remainder is 6 after subtracting 284 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
60 divided by 71 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 171908.14
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
600 divided by 71 is 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 171908.1408
Subtract 568 from 600 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
71 goes into 320 4 times with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 171908.14084
Deduct 284 from 320 and we're left 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 14:
360 divided by 71 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 171908.140845
Subtract 355 from 360 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 15:
When dividing 50 by 71, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 171908.140845
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 16:
If we divide 500 by 71, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 171908.14084507
Subtract 497 from 500 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 171908.14084507 with a remaining 3e-09.
