321371 divided by 77 
We want to figure out the number of times 321371 can be divided by 77.

Step 1:
77 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 77

On to step 2:
The number 77 fits into 32 0 times, leaving a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Bring next digit (1) of the dividend behind the 32 and repeat the process: 321 / 77

Step 3:
77 goes into 321 4 times with a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 308 away from 321, we end up with 13.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 77

Advancing to step 4:
The number 77 fits into 133 1 times, leaving a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
The remainder is 56 after subtracting 77 from 133.
Grab the next digit (7) from the dividend, add it to 56, then carry on: 567 / 77

Advancing to step 5:
77 can be fit into 567 7 times, resulting in a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 417.0
Subtracting 539 from 567 leaves us with 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 77

Advancing to step 6:
77 goes into 281 3 times with a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 4173.0
The remainder is 50 after subtracting 231 from 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 7:
500 divided by 77 is 6 with a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 4173.6
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
380 divided by 77 is 4 with a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 4173.64
Subtract 308 from 380 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 9:
When dividing 720 by 77, we get 9 with a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 4173.649
If we take 693 away from 720, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 10:
270 divided by 77 is 3 with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 4173.6493
If we take 231 away from 270, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 11:
77 goes into 390 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 4173.64935
Subtracting 385 from 390 leaves us 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.

Let's proceed to step 12:
The number 77 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 4173.64935
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.

Moving on to step 13:
77 can be fit into 500 6 times, resulting in a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 4173.6493506
The remainder is 38 after subtracting 462 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 14:
380 divided by 77 is 4 with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 4173.64935064
Subtract 308 from 380 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 4173.64935064, with a leftover of 7.2e-08.
