49749851 divided by 321 
We want to figure out the number of times 49749851 can be divided by 321.

Moving on to step 1:
When dividing 4 by 321, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 321

Moving on to step 2:
321 can be fit into 49 0 times, resulting in a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Fetch the next digit (7) from the dividend, attach it to 49 and continue: 497 / 321

On to step 3:
321 goes into 497 1 times with a remainder of 176.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 321 from 497 and we're left with 176.
Append the next digit (4) from the dividend to 176 and continue with: 1764 / 321

Going ahead to step 4:
The number 321 fits into 1764 5 times, leaving a remainder of 159.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
The remainder is 159 after subtracting 1605 from 1764.
Bring next digit (9) of the dividend behind the 159 and repeat the process: 1599 / 321

Let's proceed to step 5:
If we divide 1599 by 321, we get 4 and a remainder of 315.
Use 4 as the next digit of our solution. 
Result so far: 154.0
The remainder is 315 after subtracting 1284 from 1599.
Fetch the next digit (8) from the dividend, attach it to 315 and continue: 3158 / 321

Moving on to step 6:
321 can be fit into 3158 9 times, resulting in a remainder of 269.
Use 9 as the next digit of our solution. 
Result so far: 1549.0
Deduct 2889 from 3158 and we're left with 269.
Fetch the next digit (5) from the dividend, attach it to 269 and continue: 2695 / 321

On to step 7:
If we divide 2695 by 321, we get 8 and a remainder of 127.
Write down 8 as next digit of the result. 
Result so far: 15498.0
Deduct 2568 from 2695 and we're left with 127.
Append the next digit (1) from the dividend to 127 and continue with: 1271 / 321

Let's proceed to step 8:
If we divide 1271 by 321, we get 3 and a remainder of 308.
Put 3 as the next digit of the answer. 
Result so far: 154983.0
If we take 963 away from 1271, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 9:
3080 divided by 321 is 9 with a remainder of 191.
The next digit of our result is 9. 
Result so far: 154983.9
Deduct 2889 from 3080 and we're left with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Moving on to step 10:
The number 321 fits into 1910 5 times, leaving a remainder of 305.
The next digit of our result is 5. 
Result so far: 154983.95
The remainder is 305 after subtracting 1605 from 1910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Moving on to step 11:
If we divide 3050 by 321, we get 9 and a remainder of 161.
Use 9 as the next digit of our solution. 
Result so far: 154983.959
Subtract 2889 from 3050 to get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

On to step 12:
If we divide 1610 by 321, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 154983.9595
The remainder is 5 after subtracting 1605 from 1610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
The number 321 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 154983.9595
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
321 can be fit into 500 1 times, resulting in a remainder of 179.
The next digit of our result is 1. 
Result so far: 154983.959501
The remainder is 179 after subtracting 321 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Advancing to step 15:
321 can be fit into 1790 5 times, resulting in a remainder of 185.
The next digit of our result is 5. 
Result so far: 154983.9595015
Subtracting 1605 from 1790 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 16:
The number 321 fits into 1850 5 times, leaving a remainder of 245.
Write down 5 as next digit of the result. 
Result so far: 154983.95950155
Deduct 1605 from 1850 and we're left with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

In conclusion, the division gives 154983.95950155 with a balance of 2.45e-07.
