51141837 ÷ 804 
Let's see how many times 804 fits into 51141837.

Going ahead to step 1:
5 divided by 804 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 804

Step 2:
When dividing 51 by 804, we get 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 804

Advancing to step 3:
804 goes into 511 0 times with a remainder of 511.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 511 to get 511.
Include the next digit (4) from the dividend after 511, then repeat: 5114 / 804

On to step 4:
5114 divided by 804 is 6 with a remainder of 290.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 4824 from 5114, we get 290.
Fetch the next digit (1) from the dividend, attach it to 290 and continue: 2901 / 804

Advancing to step 5:
The number 804 fits into 2901 3 times, leaving a remainder of 489.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Deduct 2412 from 2901 and we're left with 489.
Include the next digit (8) from the dividend after 489, then repeat: 4898 / 804

Step 6:
804 goes into 4898 6 times with a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 636.0
If we take 4824 away from 4898, we end up with 74.
Grab the next digit (3) from the dividend, add it to 74, then carry on: 743 / 804

Moving on to step 7:
If we divide 743 by 804, we get 0 and a remainder of 743.
Record the quotient 0 as the next digit in the result. 
Result so far: 6360.0
Subtracting 0 from 743 leaves us with 743.
Take the next digit (7) from the dividend and append it to 743, then repeat: 7437 / 804

Let's proceed to step 8:
804 can be fit into 7437 9 times, resulting in a remainder of 201.
The number 9 becomes the next digit in our result. 
Result so far: 63609.0
If we subtract 7236 from 7437, we get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

On to step 9:
If we divide 2010 by 804, we get 2 and a remainder of 402.
The number 2 becomes the next digit in our result. 
Result so far: 63609.2
Subtract 1608 from 2010 to get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Step 10:
When dividing 4020 by 804, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 63609.25
Subtracting 4020 from 4020 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
The number 804 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 63609.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
When dividing 0 by 804, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 63609.25
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 63609.25 and a remainder of 0.0.
