71246329 ÷ 661 
We want to divide 71246329 by 661.

Going ahead to step 1:
661 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 661

Moving on to step 2:
When dividing 71 by 661, we get 0 with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Include the next digit (2) from the dividend after 71, then repeat: 712 / 661

Let's proceed to step 3:
712 divided by 661 is 1 with a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 661 from 712 to get 51.
Fetch the next digit (4) from the dividend, attach it to 51 and continue: 514 / 661

Advancing to step 4:
661 goes into 514 0 times with a remainder of 514.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 514 to get 514.
Append the next digit (6) from the dividend to 514 and continue with: 5146 / 661

Step 5:
661 can be fit into 5146 7 times, resulting in a remainder of 519.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
If we subtract 4627 from 5146, we get 519.
Bring next digit (3) of the dividend behind the 519 and repeat the process: 5193 / 661

Let's proceed to step 6:
661 can be fit into 5193 7 times, resulting in a remainder of 566.
Write down 7 as next digit of the result. 
Result so far: 1077.0
Subtracting 4627 from 5193 leaves us with 566.
Take the next digit (2) from the dividend and append it to 566, then repeat: 5662 / 661

Going ahead to step 7:
661 goes into 5662 8 times with a remainder of 374.
The number 8 becomes the next digit in our result. 
Result so far: 10778.0
Subtract 5288 from 5662 to get 374.
Append the next digit (9) from the dividend to 374 and continue with: 3749 / 661

Advancing to step 8:
When dividing 3749 by 661, we get 5 with a remainder of 444.
Write down 5 as next digit of the result. 
Result so far: 107785.0
Subtract 3305 from 3749 to get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

On to step 9:
When dividing 4440 by 661, we get 6 with a remainder of 474.
Record the quotient 6 as the next digit in the result. 
Result so far: 107785.6
Subtract 3966 from 4440 to get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Step 10:
661 can be fit into 4740 7 times, resulting in a remainder of 113.
Put 7 as the next digit of the answer. 
Result so far: 107785.67
Subtracting 4627 from 4740 leaves us with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Going ahead to step 11:
1130 divided by 661 is 1 with a remainder of 469.
The number 1 becomes the next digit in our result. 
Result so far: 107785.671
Subtracting 661 from 1130 leaves us with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Going ahead to step 12:
When dividing 4690 by 661, we get 7 with a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 107785.6717
Subtract 4627 from 4690 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 13:
661 goes into 630 0 times with a remainder of 630.
Write down 0 as next digit of the result. 
Result so far: 107785.6717
The remainder is 630 after subtracting 0 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Let's proceed to step 14:
When dividing 6300 by 661, we get 9 with a remainder of 351.
The number 9 becomes the next digit in our result. 
Result so far: 107785.671709
Subtracting 5949 from 6300 leaves us with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Step 15:
If we divide 3510 by 661, we get 5 and a remainder of 205.
The number 5 becomes the next digit in our result. 
Result so far: 107785.6717095
Deduct 3305 from 3510 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 16:
The number 661 fits into 2050 3 times, leaving a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 107785.67170953
The remainder is 67 after subtracting 1983 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The final outcome is 107785.67170953, with a leftover of 6.7e-08.
