We're dividing 74744439 by 126 
We're looking to find how many times 126 goes into 74744439.

Advancing to step 1:
If we divide 7 by 126, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 126

Let's proceed to step 2:
When dividing 74 by 126, we get 0 with a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Include the next digit (7) from the dividend after 74, then repeat: 747 / 126

On to step 3:
126 goes into 747 5 times with a remainder of 117.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 630 from 747 to get 117.
Bring next digit (4) of the dividend behind the 117 and repeat the process: 1174 / 126

Moving on to step 4:
The number 126 fits into 1174 9 times, leaving a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
The remainder is 40 after subtracting 1134 from 1174.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 126

Advancing to step 5:
126 can be fit into 404 3 times, resulting in a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 593.0
Subtract 378 from 404 to get 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 126

Advancing to step 6:
126 goes into 264 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 5932.0
Subtract 252 from 264 to get 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 126

On to step 7:
126 goes into 123 0 times with a remainder of 123.
Record the quotient 0 as the next digit in the result. 
Result so far: 59320.0
If we take 0 away from 123, we end up with 123.
Append the next digit (9) from the dividend to 123 and continue with: 1239 / 126

Advancing to step 8:
The number 126 fits into 1239 9 times, leaving a remainder of 105.
The number 9 becomes the next digit in our result. 
Result so far: 593209.0
The remainder is 105 after subtracting 1134 from 1239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 9:
126 goes into 1050 8 times with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 593209.8
Deduct 1008 from 1050 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
126 goes into 420 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 593209.83
Subtract 378 from 420 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
420 divided by 126 is 3 with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 593209.833
If we take 378 away from 420, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 593209.833, with a leftover of 0.0042.
