Let's divide 81077291 by 641
We want to divide 81077291 by 641.

On to step 1:
641 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 641

Going ahead to step 2:
81 divided by 641 is 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Bring next digit (0) of the dividend behind the 81 and repeat the process: 810 / 641

Step 3:
641 goes into 810 1 times with a remainder of 169.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 641 away from 810, we end up with 169.
Fetch the next digit (7) from the dividend, attach it to 169 and continue: 1697 / 641

Step 4:
641 can be fit into 1697 2 times, resulting in a remainder of 415.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 415 after subtracting 1282 from 1697.
Take the next digit (7) from the dividend and append it to 415, then repeat: 4157 / 641

Let's proceed to step 5:
The number 641 fits into 4157 6 times, leaving a remainder of 311.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
Subtracting 3846 from 4157 leaves us with 311.
Fetch the next digit (2) from the dividend, attach it to 311 and continue: 3112 / 641

On to step 6:
641 goes into 3112 4 times with a remainder of 548.
Use 4 as the next digit of our solution. 
Result so far: 1264.0
The remainder is 548 after subtracting 2564 from 3112.
Take the next digit (9) from the dividend and append it to 548, then repeat: 5489 / 641

Step 7:
The number 641 fits into 5489 8 times, leaving a remainder of 361.
The number 8 becomes the next digit in our result. 
Result so far: 12648.0
Subtract 5128 from 5489 to get 361.
Include the next digit (1) from the dividend after 361, then repeat: 3611 / 641

Step 8:
The number 641 fits into 3611 5 times, leaving a remainder of 406.
The number 5 becomes the next digit in our result. 
Result so far: 126485.0
If we take 3205 away from 3611, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Moving on to step 9:
If we divide 4060 by 641, we get 6 and a remainder of 214.
The number 6 becomes the next digit in our result. 
Result so far: 126485.6
The remainder is 214 after subtracting 3846 from 4060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Going ahead to step 10:
If we divide 2140 by 641, we get 3 and a remainder of 217.
Write down 3 as next digit of the result. 
Result so far: 126485.63
Subtracting 1923 from 2140 leaves us with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 11:
2170 divided by 641 is 3 with a remainder of 247.
The number 3 becomes the next digit in our result. 
Result so far: 126485.633
If we subtract 1923 from 2170, we get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

In conclusion, the division gives 126485.633 with a balance of 0.0247.
