Let's divide 5851420 by 804
Our goal is to divide 5851420 by 804.

Advancing to step 1:
If we divide 5 by 804, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 804

On to step 2:
804 goes into 58 0 times with a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 58 to get 58.
Grab the next digit (5) from the dividend, add it to 58, then carry on: 585 / 804

Going ahead to step 3:
804 can be fit into 585 0 times, resulting in a remainder of 585.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 585, we get 585.
Take the next digit (1) from the dividend and append it to 585, then repeat: 5851 / 804

Step 4:
804 goes into 5851 7 times with a remainder of 223.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 5628 from 5851, we get 223.
Bring next digit (4) of the dividend behind the 223 and repeat the process: 2234 / 804

Let's proceed to step 5:
If we divide 2234 by 804, we get 2 and a remainder of 626.
Put 2 as the next digit of the answer. 
Result so far: 72.0
If we subtract 1608 from 2234, we get 626.
Include the next digit (2) from the dividend after 626, then repeat: 6262 / 804

Advancing to step 6:
6262 divided by 804 is 7 with a remainder of 634.
Use 7 as the next digit of our solution. 
Result so far: 727.0
Deduct 5628 from 6262 and we're left with 634.
Grab the next digit (0) from the dividend, add it to 634, then carry on: 6340 / 804

Step 7:
The number 804 fits into 6340 7 times, leaving a remainder of 712.
Put 7 as the next digit of the answer. 
Result so far: 7277.0
If we subtract 5628 from 6340, we get 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Moving on to step 8:
When dividing 7120 by 804, we get 8 with a remainder of 688.
The number 8 becomes the next digit in our result. 
Result so far: 7277.8
If we take 6432 away from 7120, 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.

Moving on to step 9:
6880 divided by 804 is 8 with a remainder of 448.
Write down 8 as next digit of the result. 
Result so far: 7277.88
If we take 6432 away from 6880, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

The final outcome is 7277.88, with a leftover of 0.448.
