We're dividing 637474 by 12 
We're looking to find how many times 12 goes into 637474.

Advancing to step 1:
12 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 12

Moving on to step 2:
12 can be fit into 63 5 times, resulting in a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 60 from 63 leaves us with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 12

Advancing to step 3:
37 divided by 12 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 53.0
If we subtract 36 from 37, we get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 12

Let's proceed to step 4:
If we divide 14 by 12, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 531.0
Subtracting 12 from 14 leaves us with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 12

On to step 5:
When dividing 27 by 12, we get 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 5312.0
Subtracting 24 from 27 leaves us with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 12

On to step 6:
If we divide 34 by 12, we get 2 and a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 53122.0
Deduct 24 from 34 and we're left with 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 7:
100 divided by 12 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 53122.8
If we take 96 away from 100, we end up 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.

Moving on to step 8:
12 goes into 40 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 53122.83
Subtracting 36 from 40 leaves us 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.

Advancing to step 9:
40 divided by 12 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 53122.833
If we take 36 away from 40, we end up 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.

In conclusion, the division gives 53122.833 with a balance of 0.0004.
