We look at the division of 12239722 by 974 
Let's see how many times 974 fits into 12239722.

Step 1:
When dividing 1 by 974, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 974

Moving on to step 2:
If we divide 12 by 974, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 974

Going ahead to step 3:
974 can be fit into 122 0 times, resulting in a remainder of 122.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 122 to get 122.
Bring next digit (3) of the dividend behind the 122 and repeat the process: 1223 / 974

Step 4:
1223 divided by 974 is 1 with a remainder of 249.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 974 from 1223 to get 249.
Grab the next digit (9) from the dividend, add it to 249, then carry on: 2499 / 974

Let's proceed to step 5:
974 can be fit into 2499 2 times, resulting in a remainder of 551.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 1948 from 2499 to get 551.
Take the next digit (7) from the dividend and append it to 551, then repeat: 5517 / 974

Advancing to step 6:
974 can be fit into 5517 5 times, resulting in a remainder of 647.
The next digit of our result is 5. 
Result so far: 125.0
Subtracting 4870 from 5517 leaves us with 647.
Fetch the next digit (2) from the dividend, attach it to 647 and continue: 6472 / 974

Going ahead to step 7:
974 goes into 6472 6 times with a remainder of 628.
The next digit of our result is 6. 
Result so far: 1256.0
Subtract 5844 from 6472 to get 628.
Grab the next digit (2) from the dividend, add it to 628, then carry on: 6282 / 974

Step 8:
974 can be fit into 6282 6 times, resulting in a remainder of 438.
Use 6 as the next digit of our solution. 
Result so far: 12566.0
Subtract 5844 from 6282 to get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Moving on to step 9:
If we divide 4380 by 974, we get 4 and a remainder of 484.
Use 4 as the next digit of our solution. 
Result so far: 12566.4
If we take 3896 away from 4380, we end up with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Advancing to step 10:
If we divide 4840 by 974, we get 4 and a remainder of 944.
Write down 4 as next digit of the result. 
Result so far: 12566.44
If we subtract 3896 from 4840, we get 944.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9440, and continue the process.

After the division, we end up with 12566.44 and a remainder of 0.944.
