We look at the division of 49665874 by 321 
We're looking to find how many times 321 goes into 49665874.

Moving on to step 1:
321 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 321

Advancing to step 2:
321 can be fit into 49 0 times, resulting in a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Bring next digit (6) of the dividend behind the 49 and repeat the process: 496 / 321

Step 3:
The number 321 fits into 496 1 times, leaving a remainder of 175.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 321 from 496 leaves us with 175.
Append the next digit (6) from the dividend to 175 and continue with: 1756 / 321

On to step 4:
The number 321 fits into 1756 5 times, leaving a remainder of 151.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 1605 away from 1756, we end up with 151.
Bring next digit (5) of the dividend behind the 151 and repeat the process: 1515 / 321

Step 5:
When dividing 1515 by 321, we get 4 with a remainder of 231.
Write down 4 as next digit of the result. 
Result so far: 154.0
If we take 1284 away from 1515, we end up with 231.
Take the next digit (8) from the dividend and append it to 231, then repeat: 2318 / 321

Step 6:
2318 divided by 321 is 7 with a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 1547.0
The remainder is 71 after subtracting 2247 from 2318.
Include the next digit (7) from the dividend after 71, then repeat: 717 / 321

Moving on to step 7:
If we divide 717 by 321, we get 2 and a remainder of 75.
The next digit of our result is 2. 
Result so far: 15472.0
If we take 642 away from 717, we end up with 75.
Include the next digit (4) from the dividend after 75, then repeat: 754 / 321

Moving on to step 8:
321 goes into 754 2 times with a remainder of 112.
Use 2 as the next digit of our solution. 
Result so far: 154722.0
Deduct 642 from 754 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 9:
If we divide 1120 by 321, we get 3 and a remainder of 157.
Use 3 as the next digit of our solution. 
Result so far: 154722.3
Subtracting 963 from 1120 leaves us with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Moving on to step 10:
If we divide 1570 by 321, we get 4 and a remainder of 286.
Write down 4 as next digit of the result. 
Result so far: 154722.34
If we subtract 1284 from 1570, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Advancing to step 11:
If we divide 2860 by 321, we get 8 and a remainder of 292.
Record the quotient 8 as the next digit in the result. 
Result so far: 154722.348
Subtract 2568 from 2860 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 12:
321 can be fit into 2920 9 times, resulting in a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 154722.3489
If we take 2889 away from 2920, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 13:
If we divide 310 by 321, we get 0 and a remainder of 310.
Put 0 as the next digit of the answer. 
Result so far: 154722.3489
Subtract 0 from 310 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 14:
The number 321 fits into 3100 9 times, leaving a remainder of 211.
Write down 9 as next digit of the result. 
Result so far: 154722.348909
The remainder is 211 after subtracting 2889 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Let's proceed to step 15:
321 can be fit into 2110 6 times, resulting in a remainder of 184.
Put 6 as the next digit of the answer. 
Result so far: 154722.3489096
If we take 1926 away from 2110, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 16:
If we divide 1840 by 321, we get 5 and a remainder of 235.
Put 5 as the next digit of the answer. 
Result so far: 154722.34890965
Subtract 1605 from 1840 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

In conclusion, the division gives 154722.34890965 with a balance of 2.35e-07.
