We're dividing 39546672 by 1 
Let's see how many times 1 fits into 39546672.

Let's proceed to step 1:
When dividing 3 by 1, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 3 from 3 and we're left with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Step 2:
When dividing 9 by 1, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 39.0
If we subtract 9 from 9, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Moving on to step 3:
5 divided by 1 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 395.0
Subtract 5 from 5 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Step 4:
The number 1 fits into 4 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 3954.0
The remainder is 0 after subtracting 4 from 4.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 1

On to step 5:
1 can be fit into 6 6 times, resulting in a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 39546.0
If we subtract 6 from 6, we get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

Moving on to step 6:
The number 1 fits into 6 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 395466.0
Subtracting 6 from 6 leaves us with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

Let's proceed to step 7:
7 divided by 1 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 3954667.0
Subtract 7 from 7 to get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Let's proceed to step 8:
When dividing 2 by 1, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 39546672.0
Subtracting 2 from 2 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.

Advancing to step 9:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 39546672.0
Deduct 0 from 0 and we're left 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 10:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 39546672.0
The remainder is 0 after subtracting 0 from 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 39546672.0, with a leftover of 0.0.
