12212456 divided by 298 
Our goal is to divide 12212456 by 298.

Advancing to step 1:
When dividing 1 by 298, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 298

Moving on to step 2:
When dividing 12 by 298, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 298

Advancing to step 3:
The number 298 fits into 122 0 times, leaving a remainder of 122.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 122 after subtracting 0 from 122.
Bring next digit (1) of the dividend behind the 122 and repeat the process: 1221 / 298

Let's proceed to step 4:
The number 298 fits into 1221 4 times, leaving a remainder of 29.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 1192 from 1221 and we're left with 29.
Bring next digit (2) of the dividend behind the 29 and repeat the process: 292 / 298

Let's proceed to step 5:
When dividing 292 by 298, we get 0 with a remainder of 292.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Subtracting 0 from 292 leaves us with 292.
Grab the next digit (4) from the dividend, add it to 292, then carry on: 2924 / 298

Going ahead to step 6:
The number 298 fits into 2924 9 times, leaving a remainder of 242.
Put 9 as the next digit of the answer. 
Result so far: 409.0
If we take 2682 away from 2924, we end up with 242.
Fetch the next digit (5) from the dividend, attach it to 242 and continue: 2425 / 298

On to step 7:
298 goes into 2425 8 times with a remainder of 41.
Put 8 as the next digit of the answer. 
Result so far: 4098.0
If we subtract 2384 from 2425, we get 41.
Take the next digit (6) from the dividend and append it to 41, then repeat: 416 / 298

Let's proceed to step 8:
298 goes into 416 1 times with a remainder of 118.
The number 1 becomes the next digit in our result. 
Result so far: 40981.0
If we subtract 298 from 416, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 9:
298 goes into 1180 3 times with a remainder of 286.
The next digit of our result is 3. 
Result so far: 40981.3
The remainder is 286 after subtracting 894 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Let's proceed to step 10:
When dividing 2860 by 298, we get 9 with a remainder of 178.
The next digit of our result is 9. 
Result so far: 40981.39
If we take 2682 away from 2860, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 11:
298 goes into 1780 5 times with a remainder of 290.
Write down 5 as next digit of the result. 
Result so far: 40981.395
The remainder is 290 after subtracting 1490 from 1780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 12:
When dividing 2900 by 298, we get 9 with a remainder of 218.
The next digit of our result is 9. 
Result so far: 40981.3959
Subtract 2682 from 2900 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 13:
298 goes into 2180 7 times with a remainder of 94.
Record the quotient 7 as the next digit in the result. 
Result so far: 40981.39597
Deduct 2086 from 2180 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 14:
The number 298 fits into 940 3 times, leaving a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 40981.395973
If we subtract 894 from 940, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 15:
460 divided by 298 is 1 with a remainder of 162.
Put 1 as the next digit of the answer. 
Result so far: 40981.3959731
The remainder is 162 after subtracting 298 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Advancing to step 16:
The number 298 fits into 1620 5 times, leaving a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 40981.39597315
The remainder is 130 after subtracting 1490 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final outcome is 40981.39597315, with a leftover of 1.3e-07.
