71401766 ÷ 661 
Our goal is to divide 71401766 by 661.

Advancing to step 1:
When dividing 7 by 661, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 661

On to step 2:
When dividing 71 by 661, we get 0 with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Fetch the next digit (4) from the dividend, attach it to 71 and continue: 714 / 661

Going ahead to step 3:
661 can be fit into 714 1 times, resulting in a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 661 from 714, we get 53.
Take the next digit (0) from the dividend and append it to 53, then repeat: 530 / 661

On to step 4:
If we divide 530 by 661, we get 0 and a remainder of 530.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 530 and we're left with 530.
Append the next digit (1) from the dividend to 530 and continue with: 5301 / 661

Step 5:
If we divide 5301 by 661, we get 8 and a remainder of 13.
Put 8 as the next digit of the answer. 
Result so far: 108.0
The remainder is 13 after subtracting 5288 from 5301.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 661

On to step 6:
If we divide 137 by 661, we get 0 and a remainder of 137.
Use 0 as the next digit of our solution. 
Result so far: 1080.0
Deduct 0 from 137 and we're left with 137.
Append the next digit (6) from the dividend to 137 and continue with: 1376 / 661

Going ahead to step 7:
661 goes into 1376 2 times with a remainder of 54.
The next digit of our result is 2. 
Result so far: 10802.0
Subtracting 1322 from 1376 leaves us with 54.
Include the next digit (6) from the dividend after 54, then repeat: 546 / 661

Moving on to step 8:
661 goes into 546 0 times with a remainder of 546.
Record the quotient 0 as the next digit in the result. 
Result so far: 108020.0
Deduct 0 from 546 and we're left with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Let's proceed to step 9:
5460 divided by 661 is 8 with a remainder of 172.
The number 8 becomes the next digit in our result. 
Result so far: 108020.8
If we take 5288 away from 5460, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 10:
When dividing 1720 by 661, we get 2 with a remainder of 398.
Put 2 as the next digit of the answer. 
Result so far: 108020.82
If we subtract 1322 from 1720, we get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Moving on to step 11:
If we divide 3980 by 661, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 108020.826
If we take 3966 away from 3980, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
When dividing 140 by 661, we get 0 with a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 108020.826
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 13:
When dividing 1400 by 661, we get 2 with a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 108020.82602
If we take 1322 away from 1400, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 14:
When dividing 780 by 661, we get 1 with a remainder of 119.
Write down 1 as next digit of the result. 
Result so far: 108020.826021
Subtract 661 from 780 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 15:
When dividing 1190 by 661, we get 1 with a remainder of 529.
Record the quotient 1 as the next digit in the result. 
Result so far: 108020.8260211
If we take 661 away from 1190, we end up with 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

The final result is 108020.8260211 with a remainder of 5.29e-06.
