Let's divide 31221214 by 412
Our goal is to divide 31221214 by 412.

Advancing to step 1:
If we divide 3 by 412, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 412

Moving on to step 2:
If we divide 31 by 412, we get 0 and a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Bring next digit (2) of the dividend behind the 31 and repeat the process: 312 / 412

Advancing to step 3:
The number 412 fits into 312 0 times, leaving a remainder of 312.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 312 after subtracting 0 from 312.
Bring next digit (2) of the dividend behind the 312 and repeat the process: 3122 / 412

On to step 4:
3122 divided by 412 is 7 with a remainder of 238.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 2884 from 3122 leaves us with 238.
Grab the next digit (1) from the dividend, add it to 238, then carry on: 2381 / 412

On to step 5:
If we divide 2381 by 412, we get 5 and a remainder of 321.
The next digit of our result is 5. 
Result so far: 75.0
Subtract 2060 from 2381 to get 321.
Fetch the next digit (2) from the dividend, attach it to 321 and continue: 3212 / 412

Let's proceed to step 6:
When dividing 3212 by 412, we get 7 with a remainder of 328.
Write down 7 as next digit of the result. 
Result so far: 757.0
If we take 2884 away from 3212, we end up with 328.
Take the next digit (1) from the dividend and append it to 328, then repeat: 3281 / 412

Let's proceed to step 7:
When dividing 3281 by 412, we get 7 with a remainder of 397.
Record the quotient 7 as the next digit in the result. 
Result so far: 7577.0
Subtract 2884 from 3281 to get 397.
Append the next digit (4) from the dividend to 397 and continue with: 3974 / 412

Going ahead to step 8:
If we divide 3974 by 412, we get 9 and a remainder of 266.
Write down 9 as next digit of the result. 
Result so far: 75779.0
Subtracting 3708 from 3974 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Let's proceed to step 9:
2660 divided by 412 is 6 with a remainder of 188.
Record the quotient 6 as the next digit in the result. 
Result so far: 75779.6
If we subtract 2472 from 2660, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 10:
412 goes into 1880 4 times with a remainder of 232.
Put 4 as the next digit of the answer. 
Result so far: 75779.64
Subtracting 1648 from 1880 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 11:
The number 412 fits into 2320 5 times, leaving a remainder of 260.
The next digit of our result is 5. 
Result so far: 75779.645
Subtracting 2060 from 2320 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 12:
If we divide 2600 by 412, we get 6 and a remainder of 128.
Write down 6 as next digit of the result. 
Result so far: 75779.6456
The remainder is 128 after subtracting 2472 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 13:
If we divide 1280 by 412, we get 3 and a remainder of 44.
Use 3 as the next digit of our solution. 
Result so far: 75779.64563
Deduct 1236 from 1280 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
412 can be fit into 440 1 times, resulting in a remainder of 28.
The next digit of our result is 1. 
Result so far: 75779.645631
The remainder is 28 after subtracting 412 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 15:
280 divided by 412 is 0 with a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 75779.645631
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 16:
2800 divided by 412 is 6 with a remainder of 328.
Put 6 as the next digit of the answer. 
Result so far: 75779.64563106
Subtract 2472 from 2800 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

The quotient of the division is 75779.64563106, and the remainder is 3.28e-07.
