51558827 divided by 804 
Let's see how many times 804 fits into 51558827.

Step 1:
5 divided by 804 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 804

On to step 2:
804 goes into 51 0 times with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Append the next digit (5) from the dividend to 51 and continue with: 515 / 804

On to step 3:
804 can be fit into 515 0 times, resulting in a remainder of 515.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 515 and we're left with 515.
Take the next digit (5) from the dividend and append it to 515, then repeat: 5155 / 804

Advancing to step 4:
5155 divided by 804 is 6 with a remainder of 331.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 4824 away from 5155, we end up with 331.
Grab the next digit (8) from the dividend, add it to 331, then carry on: 3318 / 804

Let's proceed to step 5:
If we divide 3318 by 804, we get 4 and a remainder of 102.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
If we take 3216 away from 3318, we end up with 102.
Bring next digit (8) of the dividend behind the 102 and repeat the process: 1028 / 804

Step 6:
If we divide 1028 by 804, we get 1 and a remainder of 224.
Put 1 as the next digit of the answer. 
Result so far: 641.0
Subtracting 804 from 1028 leaves us with 224.
Grab the next digit (2) from the dividend, add it to 224, then carry on: 2242 / 804

Going ahead to step 7:
The number 804 fits into 2242 2 times, leaving a remainder of 634.
The number 2 becomes the next digit in our result. 
Result so far: 6412.0
Deduct 1608 from 2242 and we're left with 634.
Grab the next digit (7) from the dividend, add it to 634, then carry on: 6347 / 804

Going ahead to step 8:
When dividing 6347 by 804, we get 7 with a remainder of 719.
Put 7 as the next digit of the answer. 
Result so far: 64127.0
Deduct 5628 from 6347 and we're left with 719.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7190, and continue the process.

On to step 9:
7190 divided by 804 is 8 with a remainder of 758.
The number 8 becomes the next digit in our result. 
Result so far: 64127.8
Subtracting 6432 from 7190 leaves us with 758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7580, and continue the process.

Step 10:
The number 804 fits into 7580 9 times, leaving a remainder of 344.
The number 9 becomes the next digit in our result. 
Result so far: 64127.89
Subtract 7236 from 7580 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 11:
When dividing 3440 by 804, we get 4 with a remainder of 224.
Record the quotient 4 as the next digit in the result. 
Result so far: 64127.894
Subtract 3216 from 3440 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 12:
804 can be fit into 2240 2 times, resulting in a remainder of 632.
The next digit of our result is 2. 
Result so far: 64127.8942
Subtract 1608 from 2240 to get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

On to step 13:
When dividing 6320 by 804, we get 7 with a remainder of 692.
Put 7 as the next digit of the answer. 
Result so far: 64127.89427
The remainder is 692 after subtracting 5628 from 6320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Going ahead to step 14:
When dividing 6920 by 804, we get 8 with a remainder of 488.
The number 8 becomes the next digit in our result. 
Result so far: 64127.894278
Subtracting 6432 from 6920 leaves us with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

On to step 15:
804 can be fit into 4880 6 times, resulting in a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 64127.8942786
If we subtract 4824 from 4880, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 16:
804 goes into 560 0 times with a remainder of 560.
The number 0 becomes the next digit in our result. 
Result so far: 64127.8942786
Subtract 0 from 560 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

The final outcome is 64127.8942786, with a leftover of 5.6e-07.
