Let's divide 81294646 by 408
We want to divide 81294646 by 408.

Going ahead to step 1:
The number 408 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 408

Going ahead to step 2:
408 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
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 / 408

On to step 3:
If we divide 812 by 408, we get 1 and a remainder of 404.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 408 from 812, we get 404.
Append the next digit (9) from the dividend to 404 and continue with: 4049 / 408

Going ahead to step 4:
When dividing 4049 by 408, we get 9 with a remainder of 377.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we subtract 3672 from 4049, we get 377.
Grab the next digit (4) from the dividend, add it to 377, then carry on: 3774 / 408

Step 5:
If we divide 3774 by 408, we get 9 and a remainder of 102.
The next digit of our result is 9. 
Result so far: 199.0
Subtract 3672 from 3774 to get 102.
Fetch the next digit (6) from the dividend, attach it to 102 and continue: 1026 / 408

Let's proceed to step 6:
408 can be fit into 1026 2 times, resulting in a remainder of 210.
Write down 2 as next digit of the result. 
Result so far: 1992.0
Deduct 816 from 1026 and we're left with 210.
Include the next digit (4) from the dividend after 210, then repeat: 2104 / 408

Moving on to step 7:
The number 408 fits into 2104 5 times, leaving a remainder of 64.
The next digit of our result is 5. 
Result so far: 19925.0
Deduct 2040 from 2104 and we're left with 64.
Include the next digit (6) from the dividend after 64, then repeat: 646 / 408

Moving on to step 8:
646 divided by 408 is 1 with a remainder of 238.
The number 1 becomes the next digit in our result. 
Result so far: 199251.0
Deduct 408 from 646 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 9:
If we divide 2380 by 408, we get 5 and a remainder of 340.
Write down 5 as next digit of the result. 
Result so far: 199251.5
If we subtract 2040 from 2380, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 10:
The number 408 fits into 3400 8 times, leaving a remainder of 136.
Record the quotient 8 as the next digit in the result. 
Result so far: 199251.58
If we take 3264 away from 3400, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 11:
408 can be fit into 1360 3 times, resulting in a remainder of 136.
Use 3 as the next digit of our solution. 
Result so far: 199251.583
If we take 1224 away from 1360, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 12:
408 can be fit into 1360 3 times, resulting in a remainder of 136.
Record the quotient 3 as the next digit in the result. 
Result so far: 199251.5833
Subtract 1224 from 1360 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The quotient of the division is 199251.5833, and the remainder is 0.00136.
