668900 ÷ 71 
We want to figure out the number of times 668900 can be divided by 71.

Advancing to step 1:
6 divided by 71 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 71

Going ahead to step 2:
The number 71 fits into 66 0 times, leaving a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Append the next digit (8) from the dividend to 66 and continue with: 668 / 71

Advancing to step 3:
When dividing 668 by 71, we get 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 639 from 668 leaves us with 29.
Fetch the next digit (9) from the dividend, attach it to 29 and continue: 299 / 71

Step 4:
When dividing 299 by 71, we get 4 with a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 94.0
Subtract 284 from 299 to get 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 71

Advancing to step 5:
The number 71 fits into 150 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 942.0
Subtract 142 from 150 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 71

Let's proceed to step 6:
If we divide 80 by 71, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 9421.0
Deduct 71 from 80 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
90 divided by 71 is 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 9421.1
If we take 71 away from 90, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 8:
190 divided by 71 is 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 9421.12
Subtracting 142 from 190 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
480 divided by 71 is 6 with a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 9421.126
Subtract 426 from 480 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
If we divide 540 by 71, we get 7 and a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 9421.1267
Deduct 497 from 540 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 11:
430 divided by 71 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 9421.12676
If we take 426 away from 430, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
71 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 9421.12676
Deduct 0 from 40 and we're left 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.

On to step 13:
When dividing 400 by 71, we get 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 9421.1267605
Deduct 355 from 400 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 14:
71 goes into 450 6 times with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 9421.12676056
If we take 426 away from 450, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 9421.12676056, with a leftover of 2.4e-08.
