Let's divide 398273 by 77
We want to divide 398273 by 77.

Moving on to step 1:
The number 77 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 77

Moving on to step 2:
77 can be fit into 39 0 times, resulting in a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 77

Let's proceed to step 3:
The number 77 fits into 398 5 times, leaving a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 385 away from 398, we end up with 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 77

Let's proceed to step 4:
77 can be fit into 132 1 times, resulting in a remainder of 55.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtracting 77 from 132 leaves us with 55.
Bring next digit (7) of the dividend behind the 55 and repeat the process: 557 / 77

Advancing to step 5:
When dividing 557 by 77, we get 7 with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 517.0
Deduct 539 from 557 and we're left with 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 77

Let's proceed to step 6:
183 divided by 77 is 2 with a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 5172.0
If we subtract 154 from 183, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
When dividing 290 by 77, we get 3 with a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 5172.3
Subtract 231 from 290 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 8:
If we divide 590 by 77, we get 7 and a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 5172.37
Subtracting 539 from 590 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 9:
77 can be fit into 510 6 times, resulting in a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 5172.376
If we subtract 462 from 510, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
If we divide 480 by 77, we get 6 and a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 5172.3766
If we take 462 away from 480, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 5172.3766 and a remainder of 0.00018.
