27634886 ÷ 641 
Let's see how many times 641 fits into 27634886.

Advancing to step 1:
If we divide 2 by 641, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 641

On to step 2:
27 divided by 641 is 0 with a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 27 to get 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 641

Step 3:
When dividing 276 by 641, we get 0 with a remainder of 276.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 276 leaves us with 276.
Include the next digit (3) from the dividend after 276, then repeat: 2763 / 641

Moving on to step 4:
The number 641 fits into 2763 4 times, leaving a remainder of 199.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 2564 from 2763 and we're left with 199.
Grab the next digit (4) from the dividend, add it to 199, then carry on: 1994 / 641

Moving on to step 5:
If we divide 1994 by 641, we get 3 and a remainder of 71.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Subtracting 1923 from 1994 leaves us with 71.
Append the next digit (8) from the dividend to 71 and continue with: 718 / 641

On to step 6:
The number 641 fits into 718 1 times, leaving a remainder of 77.
The number 1 becomes the next digit in our result. 
Result so far: 431.0
If we take 641 away from 718, we end up with 77.
Append the next digit (8) from the dividend to 77 and continue with: 778 / 641

Step 7:
The number 641 fits into 778 1 times, leaving a remainder of 137.
Put 1 as the next digit of the answer. 
Result so far: 4311.0
If we take 641 away from 778, we end up with 137.
Grab the next digit (6) from the dividend, add it to 137, then carry on: 1376 / 641

On to step 8:
1376 divided by 641 is 2 with a remainder of 94.
Put 2 as the next digit of the answer. 
Result so far: 43112.0
Subtracting 1282 from 1376 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 9:
If we divide 940 by 641, we get 1 and a remainder of 299.
The number 1 becomes the next digit in our result. 
Result so far: 43112.1
If we subtract 641 from 940, we get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Going ahead to step 10:
When dividing 2990 by 641, we get 4 with a remainder of 426.
Write down 4 as next digit of the result. 
Result so far: 43112.14
If we subtract 2564 from 2990, we get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Going ahead to step 11:
4260 divided by 641 is 6 with a remainder of 414.
Write down 6 as next digit of the result. 
Result so far: 43112.146
Subtract 3846 from 4260 to get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Advancing to step 12:
641 can be fit into 4140 6 times, resulting in a remainder of 294.
Record the quotient 6 as the next digit in the result. 
Result so far: 43112.1466
Deduct 3846 from 4140 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

After the division, we end up with 43112.1466 and a remainder of 0.00294.
