57637390 ÷ 804 
Our goal is to divide 57637390 by 804.

Step 1:
When dividing 5 by 804, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 804

Step 2:
804 goes into 57 0 times with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Grab the next digit (6) from the dividend, add it to 57, then carry on: 576 / 804

Step 3:
The number 804 fits into 576 0 times, leaving a remainder of 576.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 576 and we're left with 576.
Bring next digit (3) of the dividend behind the 576 and repeat the process: 5763 / 804

Moving on to step 4:
804 can be fit into 5763 7 times, resulting in a remainder of 135.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 5628 from 5763 to get 135.
Grab the next digit (7) from the dividend, add it to 135, then carry on: 1357 / 804

Step 5:
When dividing 1357 by 804, we get 1 with a remainder of 553.
Write down 1 as next digit of the result. 
Result so far: 71.0
Deduct 804 from 1357 and we're left with 553.
Include the next digit (3) from the dividend after 553, then repeat: 5533 / 804

On to step 6:
804 goes into 5533 6 times with a remainder of 709.
The next digit of our result is 6. 
Result so far: 716.0
Subtracting 4824 from 5533 leaves us with 709.
Grab the next digit (9) from the dividend, add it to 709, then carry on: 7099 / 804

Let's proceed to step 7:
804 can be fit into 7099 8 times, resulting in a remainder of 667.
Write down 8 as next digit of the result. 
Result so far: 7168.0
If we take 6432 away from 7099, we end up with 667.
Append the next digit (0) from the dividend to 667 and continue with: 6670 / 804

Let's proceed to step 8:
When dividing 6670 by 804, we get 8 with a remainder of 238.
Put 8 as the next digit of the answer. 
Result so far: 71688.0
The remainder is 238 after subtracting 6432 from 6670.
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:
When dividing 2380 by 804, we get 2 with a remainder of 772.
Record the quotient 2 as the next digit in the result. 
Result so far: 71688.2
The remainder is 772 after subtracting 1608 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Step 10:
804 can be fit into 7720 9 times, resulting in a remainder of 484.
Write down 9 as next digit of the result. 
Result so far: 71688.29
If we subtract 7236 from 7720, we get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Advancing to step 11:
4840 divided by 804 is 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 71688.296
If we subtract 4824 from 4840, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
When dividing 160 by 804, we get 0 with a remainder of 160.
The next digit of our result is 0. 
Result so far: 71688.296
Deduct 0 from 160 and we're left 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.

Let's proceed to step 13:
1600 divided by 804 is 1 with a remainder of 796.
The number 1 becomes the next digit in our result. 
Result so far: 71688.29601
Subtracting 804 from 1600 leaves us with 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Step 14:
804 can be fit into 7960 9 times, resulting in a remainder of 724.
Record the quotient 9 as the next digit in the result. 
Result so far: 71688.296019
If we subtract 7236 from 7960, we get 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

On to step 15:
804 can be fit into 7240 9 times, resulting in a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 71688.2960199
Subtracting 7236 from 7240 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 71688.2960199 and a remainder of 4e-08.
