77854040 divided by 321 
We want to divide 77854040 by 321.

Advancing to step 1:
321 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 321

On to step 2:
321 can be fit into 77 0 times, resulting in a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Bring next digit (8) of the dividend behind the 77 and repeat the process: 778 / 321

Let's proceed to step 3:
778 divided by 321 is 2 with a remainder of 136.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 642 away from 778, we end up with 136.
Include the next digit (5) from the dividend after 136, then repeat: 1365 / 321

Going ahead to step 4:
321 can be fit into 1365 4 times, resulting in a remainder of 81.
The next digit of our result is 4. 
Result so far: 24.0
Subtracting 1284 from 1365 leaves us with 81.
Grab the next digit (4) from the dividend, add it to 81, then carry on: 814 / 321

Step 5:
If we divide 814 by 321, we get 2 and a remainder of 172.
Record the quotient 2 as the next digit in the result. 
Result so far: 242.0
Deduct 642 from 814 and we're left with 172.
Grab the next digit (0) from the dividend, add it to 172, then carry on: 1720 / 321

Step 6:
321 goes into 1720 5 times with a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 2425.0
If we subtract 1605 from 1720, we get 115.
Grab the next digit (4) from the dividend, add it to 115, then carry on: 1154 / 321

On to step 7:
1154 divided by 321 is 3 with a remainder of 191.
Record the quotient 3 as the next digit in the result. 
Result so far: 24253.0
Subtracting 963 from 1154 leaves us with 191.
Bring next digit (0) of the dividend behind the 191 and repeat the process: 1910 / 321

Going ahead to step 8:
1910 divided by 321 is 5 with a remainder of 305.
Record the quotient 5 as the next digit in the result. 
Result so far: 242535.0
Subtracting 1605 from 1910 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

On to step 9:
The number 321 fits into 3050 9 times, leaving a remainder of 161.
Put 9 as the next digit of the answer. 
Result so far: 242535.9
The remainder is 161 after subtracting 2889 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Let's proceed to step 10:
1610 divided by 321 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 242535.95
Deduct 1605 from 1610 and we're left with 5.
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 11:
If we divide 50 by 321, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 242535.95
Subtracting 0 from 50 leaves us 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.

Advancing to step 12:
321 goes into 500 1 times with a remainder of 179.
The next digit of our result is 1. 
Result so far: 242535.9501
If we subtract 321 from 500, we get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

On to step 13:
1790 divided by 321 is 5 with a remainder of 185.
The next digit of our result is 5. 
Result so far: 242535.95015
The remainder is 185 after subtracting 1605 from 1790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 14:
321 goes into 1850 5 times with a remainder of 245.
Put 5 as the next digit of the answer. 
Result so far: 242535.950155
If we subtract 1605 from 1850, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Our division results in 242535.950155 with a remaining 2.45e-05.
