We're dividing 772121 by 31 
Let's see how many times 31 fits into 772121.

On to step 1:
The number 31 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 31

Moving on to step 2:
77 divided by 31 is 2 with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 62 from 77 and we're left with 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 31

Let's proceed to step 3:
If we divide 152 by 31, we get 4 and a remainder of 28.
The next digit of our result is 4. 
Result so far: 24.0
If we take 124 away from 152, we end up with 28.
Bring next digit (1) of the dividend behind the 28 and repeat the process: 281 / 31

Step 4:
31 can be fit into 281 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 249.0
Subtract 279 from 281 to get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 31

Advancing to step 5:
31 can be fit into 22 0 times, resulting in a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 2490.0
The remainder is 22 after subtracting 0 from 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 31

Let's proceed to step 6:
31 goes into 221 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 24907.0
Deduct 217 from 221 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
When dividing 40 by 31, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 24907.1
Subtract 31 from 40 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 8:
The number 31 fits into 90 2 times, leaving a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 24907.12
Deduct 62 from 90 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
When dividing 280 by 31, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 24907.129
Subtracting 279 from 280 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 10:
The number 31 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 24907.129
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
If we divide 100 by 31, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 24907.12903
The remainder is 7 after subtracting 93 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 12:
When dividing 70 by 31, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 24907.129032
The remainder is 8 after subtracting 62 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
80 divided by 31 is 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 24907.1290322
Subtract 62 from 80 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 24907.1290322 with a balance of 1.8e-07.
