61646631 ÷ 711 
Let's see how many times 711 fits into 61646631.

Advancing to step 1:
6 divided by 711 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 711

Step 2:
The number 711 fits into 61 0 times, leaving a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Include the next digit (6) from the dividend after 61, then repeat: 616 / 711

Step 3:
The number 711 fits into 616 0 times, leaving a remainder of 616.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 616 leaves us with 616.
Append the next digit (4) from the dividend to 616 and continue with: 6164 / 711

Step 4:
If we divide 6164 by 711, we get 8 and a remainder of 476.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 5688 away from 6164, we end up with 476.
Fetch the next digit (6) from the dividend, attach it to 476 and continue: 4766 / 711

On to step 5:
711 can be fit into 4766 6 times, resulting in a remainder of 500.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Subtracting 4266 from 4766 leaves us with 500.
Grab the next digit (6) from the dividend, add it to 500, then carry on: 5006 / 711

Let's proceed to step 6:
If we divide 5006 by 711, we get 7 and a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 867.0
Subtracting 4977 from 5006 leaves us with 29.
Take the next digit (3) from the dividend and append it to 29, then repeat: 293 / 711

Going ahead to step 7:
711 goes into 293 0 times with a remainder of 293.
Record the quotient 0 as the next digit in the result. 
Result so far: 8670.0
Subtract 0 from 293 to get 293.
Bring next digit (1) of the dividend behind the 293 and repeat the process: 2931 / 711

On to step 8:
711 can be fit into 2931 4 times, resulting in a remainder of 87.
The number 4 becomes the next digit in our result. 
Result so far: 86704.0
Subtracting 2844 from 2931 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 9:
When dividing 870 by 711, we get 1 with a remainder of 159.
Put 1 as the next digit of the answer. 
Result so far: 86704.1
If we subtract 711 from 870, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 10:
1590 divided by 711 is 2 with a remainder of 168.
Use 2 as the next digit of our solution. 
Result so far: 86704.12
If we subtract 1422 from 1590, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 11:
When dividing 1680 by 711, we get 2 with a remainder of 258.
Record the quotient 2 as the next digit in the result. 
Result so far: 86704.122
If we take 1422 away from 1680, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

The final result is 86704.122 with a remainder of 0.0258.
