We're dividing 74243137 by 10 
Our goal is to divide 74243137 by 10.

Going ahead to step 1:
The number 10 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 10

Let's proceed to step 2:
If we divide 74 by 10, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 70 from 74 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 10

Moving on to step 3:
If we divide 42 by 10, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 74.0
If we subtract 40 from 42, we get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 10

Let's proceed to step 4:
When dividing 24 by 10, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 742.0
Deduct 20 from 24 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 10

Advancing to step 5:
10 goes into 43 4 times with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 7424.0
Subtract 40 from 43 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 10

Step 6:
10 goes into 31 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 74243.0
Subtract 30 from 31 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 10

Advancing to step 7:
If we divide 13 by 10, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 742431.0
Subtracting 10 from 13 leaves us with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 10

Step 8:
10 can be fit into 37 3 times, resulting in a remainder of 7.
The next digit of our result is 3. 
Result so far: 7424313.0
Deduct 30 from 37 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
10 can be fit into 70 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 7424313.7
Subtract 70 from 70 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7424313.7
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
When dividing 0 by 10, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7424313.7
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 7424313.7, with a leftover of 0.0.
