We look at the division of 81205779 by 661 
Let's see how many times 661 fits into 81205779.

Advancing to step 1:
When dividing 8 by 661, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 661

Advancing to step 2:
When dividing 81 by 661, we get 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Bring next digit (2) of the dividend behind the 81 and repeat the process: 812 / 661

Let's proceed to step 3:
If we divide 812 by 661, we get 1 and a remainder of 151.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 151 after subtracting 661 from 812.
Bring next digit (0) of the dividend behind the 151 and repeat the process: 1510 / 661

Moving on to step 4:
When dividing 1510 by 661, we get 2 with a remainder of 188.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 1322 from 1510 leaves us with 188.
Fetch the next digit (5) from the dividend, attach it to 188 and continue: 1885 / 661

Moving on to step 5:
661 can be fit into 1885 2 times, resulting in a remainder of 563.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
If we take 1322 away from 1885, we end up with 563.
Bring next digit (7) of the dividend behind the 563 and repeat the process: 5637 / 661

Moving on to step 6:
If we divide 5637 by 661, we get 8 and a remainder of 349.
Use 8 as the next digit of our solution. 
Result so far: 1228.0
If we subtract 5288 from 5637, we get 349.
Grab the next digit (7) from the dividend, add it to 349, then carry on: 3497 / 661

Advancing to step 7:
The number 661 fits into 3497 5 times, leaving a remainder of 192.
Put 5 as the next digit of the answer. 
Result so far: 12285.0
The remainder is 192 after subtracting 3305 from 3497.
Take the next digit (9) from the dividend and append it to 192, then repeat: 1929 / 661

Let's proceed to step 8:
When dividing 1929 by 661, we get 2 with a remainder of 607.
Write down 2 as next digit of the result. 
Result so far: 122852.0
The remainder is 607 after subtracting 1322 from 1929.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Going ahead to step 9:
661 goes into 6070 9 times with a remainder of 121.
Use 9 as the next digit of our solution. 
Result so far: 122852.9
Subtract 5949 from 6070 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 10:
When dividing 1210 by 661, we get 1 with a remainder of 549.
The number 1 becomes the next digit in our result. 
Result so far: 122852.91
Subtract 661 from 1210 to get 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Going ahead to step 11:
661 can be fit into 5490 8 times, resulting in a remainder of 202.
Put 8 as the next digit of the answer. 
Result so far: 122852.918
If we subtract 5288 from 5490, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 12:
661 can be fit into 2020 3 times, resulting in a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 122852.9183
Subtracting 1983 from 2020 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 13:
370 divided by 661 is 0 with a remainder of 370.
Record the quotient 0 as the next digit in the result. 
Result so far: 122852.9183
Subtracting 0 from 370 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 14:
661 can be fit into 3700 5 times, resulting in a remainder of 395.
Use 5 as the next digit of our solution. 
Result so far: 122852.918305
If we subtract 3305 from 3700, we get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Advancing to step 15:
3950 divided by 661 is 5 with a remainder of 645.
Write down 5 as next digit of the result. 
Result so far: 122852.9183055
Subtracting 3305 from 3950 leaves us with 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

In conclusion, the division gives 122852.9183055 with a balance of 6.45e-06.
