We're dividing 45486493 by 39 
Let's see how many times 39 fits into 45486493.

Advancing to step 1:
4 divided by 39 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 39

Let's proceed to step 2:
45 divided by 39 is 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 39 from 45, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 39

Let's proceed to step 3:
If we divide 64 by 39, we get 1 and a remainder of 25.
The next digit of our result is 1. 
Result so far: 11.0
If we take 39 away from 64, we end up with 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 39

Let's proceed to step 4:
39 can be fit into 258 6 times, resulting in a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 116.0
If we take 234 away from 258, we end up with 24.
Take the next digit (6) from the dividend and append it to 24, then repeat: 246 / 39

Let's proceed to step 5:
39 goes into 246 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 1166.0
The remainder is 12 after subtracting 234 from 246.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 39

Advancing to step 6:
The number 39 fits into 124 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 11663.0
Subtracting 117 from 124 leaves us with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 39

Let's proceed to step 7:
79 divided by 39 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 116632.0
Deduct 78 from 79 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 39

Let's proceed to step 8:
13 divided by 39 is 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 1166320.0
Subtract 0 from 13 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
If we divide 130 by 39, we get 3 and a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 1166320.3
If we subtract 117 from 130, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 10:
39 goes into 130 3 times with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 1166320.33
Subtracting 117 from 130 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 1166320.33 with a balance of 0.013.
