We look at the division of 46899878 by 809 
Let's see how many times 809 fits into 46899878.

Let's proceed to step 1:
When dividing 4 by 809, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 809

Step 2:
809 can be fit into 46 0 times, resulting in a remainder of 46.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 46, we end up with 46.
Grab the next digit (8) from the dividend, add it to 46, then carry on: 468 / 809

On to step 3:
468 divided by 809 is 0 with a remainder of 468.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 468 leaves us with 468.
Take the next digit (9) from the dividend and append it to 468, then repeat: 4689 / 809

Moving on to step 4:
When dividing 4689 by 809, we get 5 with a remainder of 644.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 4045 from 4689 to get 644.
Take the next digit (9) from the dividend and append it to 644, then repeat: 6449 / 809

Step 5:
The number 809 fits into 6449 7 times, leaving a remainder of 786.
The next digit of our result is 7. 
Result so far: 57.0
If we subtract 5663 from 6449, we get 786.
Grab the next digit (8) from the dividend, add it to 786, then carry on: 7868 / 809

Going ahead to step 6:
If we divide 7868 by 809, we get 9 and a remainder of 587.
The next digit of our result is 9. 
Result so far: 579.0
Subtracting 7281 from 7868 leaves us with 587.
Append the next digit (7) from the dividend to 587 and continue with: 5877 / 809

Step 7:
The number 809 fits into 5877 7 times, leaving a remainder of 214.
Use 7 as the next digit of our solution. 
Result so far: 5797.0
If we take 5663 away from 5877, we end up with 214.
Grab the next digit (8) from the dividend, add it to 214, then carry on: 2148 / 809

Advancing to step 8:
809 goes into 2148 2 times with a remainder of 530.
Record the quotient 2 as the next digit in the result. 
Result so far: 57972.0
Subtract 1618 from 2148 to get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Let's proceed to step 9:
If we divide 5300 by 809, we get 6 and a remainder of 446.
Use 6 as the next digit of our solution. 
Result so far: 57972.6
Deduct 4854 from 5300 and we're left with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Let's proceed to step 10:
The number 809 fits into 4460 5 times, leaving a remainder of 415.
Record the quotient 5 as the next digit in the result. 
Result so far: 57972.65
Subtract 4045 from 4460 to get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Step 11:
809 goes into 4150 5 times with a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 57972.655
Deduct 4045 from 4150 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The quotient of the division is 57972.655, and the remainder is 0.0105.
