Let's divide 81609153 by 404
Let's see how many times 404 fits into 81609153.

Advancing to step 1:
404 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 404

Let's proceed to step 2:
404 can be fit into 81 0 times, resulting in a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Bring next digit (6) of the dividend behind the 81 and repeat the process: 816 / 404

On to step 3:
When dividing 816 by 404, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 808 from 816 leaves us with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 404

On to step 4:
80 divided by 404 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 80, we end up with 80.
Take the next digit (9) from the dividend and append it to 80, then repeat: 809 / 404

Advancing to step 5:
If we divide 809 by 404, we get 2 and a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 202.0
Deduct 808 from 809 and we're left with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 404

Advancing to step 6:
The number 404 fits into 11 0 times, leaving a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 2020.0
If we subtract 0 from 11, we get 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 404

Let's proceed to step 7:
404 goes into 115 0 times with a remainder of 115.
The number 0 becomes the next digit in our result. 
Result so far: 20200.0
Subtract 0 from 115 to get 115.
Fetch the next digit (3) from the dividend, attach it to 115 and continue: 1153 / 404

On to step 8:
1153 divided by 404 is 2 with a remainder of 345.
Write down 2 as next digit of the result. 
Result so far: 202002.0
Deduct 808 from 1153 and we're left with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

On to step 9:
The number 404 fits into 3450 8 times, leaving a remainder of 218.
Record the quotient 8 as the next digit in the result. 
Result so far: 202002.8
Subtracting 3232 from 3450 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 10:
If we divide 2180 by 404, we get 5 and a remainder of 160.
Record the quotient 5 as the next digit in the result. 
Result so far: 202002.85
If we subtract 2020 from 2180, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 11:
404 can be fit into 1600 3 times, resulting in a remainder of 388.
Write down 3 as next digit of the result. 
Result so far: 202002.853
Subtracting 1212 from 1600 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Step 12:
If we divide 3880 by 404, we get 9 and a remainder of 244.
Use 9 as the next digit of our solution. 
Result so far: 202002.8539
Subtract 3636 from 3880 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Going ahead to step 13:
404 can be fit into 2440 6 times, resulting in a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 202002.85396
Subtracting 2424 from 2440 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
When dividing 160 by 404, we get 0 with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 202002.85396
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 15:
1600 divided by 404 is 3 with a remainder of 388.
The number 3 becomes the next digit in our result. 
Result so far: 202002.8539603
Deduct 1212 from 1600 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 16:
404 can be fit into 3880 9 times, resulting in a remainder of 244.
Put 9 as the next digit of the answer. 
Result so far: 202002.85396039
If we subtract 3636 from 3880, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

After the division, we end up with 202002.85396039 and a remainder of 2.44e-07.
