We're dividing 31921 by 77 
We want to figure out the number of times 31921 can be divided by 77.

Let's proceed to step 1:
77 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 77

Let's proceed to step 2:
31 divided by 77 is 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Include the next digit (9) from the dividend after 31, then repeat: 319 / 77

Step 3:
77 can be fit into 319 4 times, resulting in a remainder of 11.
The next digit of our result is 4. 
Result so far: 4.0
If we take 308 away from 319, we end up with 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 77

Advancing to step 4:
112 divided by 77 is 1 with a remainder of 35.
The next digit of our result is 1. 
Result so far: 41.0
Subtract 77 from 112 to get 35.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 77

Going ahead to step 5:
77 goes into 351 4 times with a remainder of 43.
Use 4 as the next digit of our solution. 
Result so far: 414.0
The remainder is 43 after subtracting 308 from 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 6:
77 can be fit into 430 5 times, resulting in a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 414.5
If we take 385 away from 430, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
If we divide 450 by 77, we get 5 and a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 414.55
If we take 385 away from 450, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The quotient of the division is 414.55, and the remainder is 0.065.
