53703429 divided by 808 
We want to figure out the number of times 53703429 can be divided by 808.

Going ahead to step 1:
When dividing 5 by 808, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 808

Let's proceed to step 2:
When dividing 53 by 808, we get 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Grab the next digit (7) from the dividend, add it to 53, then carry on: 537 / 808

Moving on to step 3:
808 can be fit into 537 0 times, resulting in a remainder of 537.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 537, we end up with 537.
Take the next digit (0) from the dividend and append it to 537, then repeat: 5370 / 808

Let's proceed to step 4:
808 can be fit into 5370 6 times, resulting in a remainder of 522.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 4848 from 5370 leaves us with 522.
Bring next digit (3) of the dividend behind the 522 and repeat the process: 5223 / 808

Let's proceed to step 5:
The number 808 fits into 5223 6 times, leaving a remainder of 375.
Put 6 as the next digit of the answer. 
Result so far: 66.0
Deduct 4848 from 5223 and we're left with 375.
Fetch the next digit (4) from the dividend, attach it to 375 and continue: 3754 / 808

Step 6:
808 goes into 3754 4 times with a remainder of 522.
Put 4 as the next digit of the answer. 
Result so far: 664.0
If we subtract 3232 from 3754, we get 522.
Grab the next digit (2) from the dividend, add it to 522, then carry on: 5222 / 808

Going ahead to step 7:
808 goes into 5222 6 times with a remainder of 374.
Record the quotient 6 as the next digit in the result. 
Result so far: 6646.0
Subtracting 4848 from 5222 leaves us with 374.
Bring next digit (9) of the dividend behind the 374 and repeat the process: 3749 / 808

On to step 8:
3749 divided by 808 is 4 with a remainder of 517.
Record the quotient 4 as the next digit in the result. 
Result so far: 66464.0
If we take 3232 away from 3749, we end up with 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Moving on to step 9:
808 can be fit into 5170 6 times, resulting in a remainder of 322.
Write down 6 as next digit of the result. 
Result so far: 66464.6
If we take 4848 away from 5170, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 10:
808 can be fit into 3220 3 times, resulting in a remainder of 796.
Record the quotient 3 as the next digit in the result. 
Result so far: 66464.63
If we subtract 2424 from 3220, we get 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Advancing to step 11:
808 goes into 7960 9 times with a remainder of 688.
Put 9 as the next digit of the answer. 
Result so far: 66464.639
If we take 7272 away from 7960, we end up with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

On to step 12:
808 can be fit into 6880 8 times, resulting in a remainder of 416.
Use 8 as the next digit of our solution. 
Result so far: 66464.6398
Deduct 6464 from 6880 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 13:
When dividing 4160 by 808, we get 5 with a remainder of 120.
The next digit of our result is 5. 
Result so far: 66464.63985
The remainder is 120 after subtracting 4040 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 14:
808 can be fit into 1200 1 times, resulting in a remainder of 392.
Write down 1 as next digit of the result. 
Result so far: 66464.639851
Subtract 808 from 1200 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Step 15:
When dividing 3920 by 808, we get 4 with a remainder of 688.
Write down 4 as next digit of the result. 
Result so far: 66464.6398514
Deduct 3232 from 3920 and we're left with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Advancing to step 16:
If we divide 6880 by 808, we get 8 and a remainder of 416.
The number 8 becomes the next digit in our result. 
Result so far: 66464.63985148
Subtract 6464 from 6880 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Our division results in 66464.63985148 with a remaining 4.16e-07.
