We look at the division of 42120169 by 744 
Our goal is to divide 42120169 by 744.

Let's proceed to step 1:
When dividing 4 by 744, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 744

Step 2:
If we divide 42 by 744, we get 0 and a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 744

Let's proceed to step 3:
If we divide 421 by 744, we get 0 and a remainder of 421.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 421 after subtracting 0 from 421.
Include the next digit (2) from the dividend after 421, then repeat: 4212 / 744

Step 4:
744 goes into 4212 5 times with a remainder of 492.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 3720 from 4212 to get 492.
Bring next digit (0) of the dividend behind the 492 and repeat the process: 4920 / 744

Step 5:
744 goes into 4920 6 times with a remainder of 456.
Use 6 as the next digit of our solution. 
Result so far: 56.0
Deduct 4464 from 4920 and we're left with 456.
Bring next digit (1) of the dividend behind the 456 and repeat the process: 4561 / 744

Moving on to step 6:
4561 divided by 744 is 6 with a remainder of 97.
Put 6 as the next digit of the answer. 
Result so far: 566.0
Subtracting 4464 from 4561 leaves us with 97.
Append the next digit (6) from the dividend to 97 and continue with: 976 / 744

Let's proceed to step 7:
The number 744 fits into 976 1 times, leaving a remainder of 232.
Write down 1 as next digit of the result. 
Result so far: 5661.0
Deduct 744 from 976 and we're left with 232.
Take the next digit (9) from the dividend and append it to 232, then repeat: 2329 / 744

Going ahead to step 8:
744 can be fit into 2329 3 times, resulting in a remainder of 97.
Record the quotient 3 as the next digit in the result. 
Result so far: 56613.0
The remainder is 97 after subtracting 2232 from 2329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Going ahead to step 9:
When dividing 970 by 744, we get 1 with a remainder of 226.
Write down 1 as next digit of the result. 
Result so far: 56613.1
If we take 744 away from 970, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Going ahead to step 10:
The number 744 fits into 2260 3 times, leaving a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 56613.13
If we take 2232 away from 2260, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
280 divided by 744 is 0 with a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 56613.13
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 12:
744 can be fit into 2800 3 times, resulting in a remainder of 568.
Put 3 as the next digit of the answer. 
Result so far: 56613.1303
Subtracting 2232 from 2800 leaves us with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Going ahead to step 13:
If we divide 5680 by 744, we get 7 and a remainder of 472.
The next digit of our result is 7. 
Result so far: 56613.13037
Deduct 5208 from 5680 and we're left with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Advancing to step 14:
4720 divided by 744 is 6 with a remainder of 256.
Put 6 as the next digit of the answer. 
Result so far: 56613.130376
If we take 4464 away from 4720, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 15:
2560 divided by 744 is 3 with a remainder of 328.
The number 3 becomes the next digit in our result. 
Result so far: 56613.1303763
Deduct 2232 from 2560 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 16:
3280 divided by 744 is 4 with a remainder of 304.
Write down 4 as next digit of the result. 
Result so far: 56613.13037634
Deduct 2976 from 3280 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

The final result is 56613.13037634 with a remainder of 3.04e-07.
