81296162 divided by 661 
We want to divide 81296162 by 661.

Let's proceed to step 1:
8 divided by 661 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 661

Step 2:
661 goes into 81 0 times with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 661

Advancing to step 3:
661 goes into 812 1 times with a remainder of 151.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 151 after subtracting 661 from 812.
Append the next digit (9) from the dividend to 151 and continue with: 1519 / 661

Going ahead to step 4:
When dividing 1519 by 661, we get 2 with a remainder of 197.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 197 after subtracting 1322 from 1519.
Include the next digit (6) from the dividend after 197, then repeat: 1976 / 661

On to step 5:
661 goes into 1976 2 times with a remainder of 654.
Write down 2 as next digit of the result. 
Result so far: 122.0
Subtract 1322 from 1976 to get 654.
Append the next digit (1) from the dividend to 654 and continue with: 6541 / 661

Step 6:
When dividing 6541 by 661, we get 9 with a remainder of 592.
Write down 9 as next digit of the result. 
Result so far: 1229.0
Deduct 5949 from 6541 and we're left with 592.
Bring next digit (6) of the dividend behind the 592 and repeat the process: 5926 / 661

Advancing to step 7:
The number 661 fits into 5926 8 times, leaving a remainder of 638.
Put 8 as the next digit of the answer. 
Result so far: 12298.0
Deduct 5288 from 5926 and we're left with 638.
Take the next digit (2) from the dividend and append it to 638, then repeat: 6382 / 661

Going ahead to step 8:
When dividing 6382 by 661, we get 9 with a remainder of 433.
Put 9 as the next digit of the answer. 
Result so far: 122989.0
Subtract 5949 from 6382 to get 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Advancing to step 9:
661 goes into 4330 6 times with a remainder of 364.
The number 6 becomes the next digit in our result. 
Result so far: 122989.6
The remainder is 364 after subtracting 3966 from 4330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 10:
The number 661 fits into 3640 5 times, leaving a remainder of 335.
Write down 5 as next digit of the result. 
Result so far: 122989.65
If we take 3305 away from 3640, we end up with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Moving on to step 11:
If we divide 3350 by 661, we get 5 and a remainder of 45.
The next digit of our result is 5. 
Result so far: 122989.655
Deduct 3305 from 3350 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.

In conclusion, the division gives 122989.655 with a balance of 0.0045.
