We're dividing 39432 by 77 
We want to figure out the number of times 39432 can be divided by 77.

Let's proceed to step 1:
If we divide 3 by 77, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 77

Moving on to step 2:
The number 77 fits into 39 0 times, leaving a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Include the next digit (4) from the dividend after 39, then repeat: 394 / 77

On to step 3:
When dividing 394 by 77, we get 5 with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 385 from 394 leaves us with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 77

Step 4:
If we divide 93 by 77, we get 1 and a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 51.0
The remainder is 16 after subtracting 77 from 93.
Take the next digit (2) from the dividend and append it to 16, then repeat: 162 / 77

Step 5:
77 can be fit into 162 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 512.0
If we subtract 154 from 162, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 6:
When dividing 80 by 77, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 512.1
Subtracting 77 from 80 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
77 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 512.1
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
300 divided by 77 is 3 with a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 512.103
Subtracting 231 from 300 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 9:
The number 77 fits into 690 8 times, leaving a remainder of 74.
The next digit of our result is 8. 
Result so far: 512.1038
If we subtract 616 from 690, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 10:
If we divide 740 by 77, we get 9 and a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 512.10389
Deduct 693 from 740 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 11:
If we divide 470 by 77, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 512.103896
Subtracting 462 from 470 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
When dividing 80 by 77, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 512.1038961
If we subtract 77 from 80, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 13:
77 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 512.1038961
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 512.1038961, with a leftover of 3e-08.
