45984 divided by 39 
We want to figure out the number of times 45984 can be divided by 39.

Moving on to step 1:
When dividing 4 by 39, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 39

On to step 2:
When dividing 45 by 39, we get 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 39 from 45 to get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 39

Moving on to step 3:
39 can be fit into 69 1 times, resulting in a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 39 from 69 leaves us with 30.
Append the next digit (8) from the dividend to 30 and continue with: 308 / 39

Step 4:
39 can be fit into 308 7 times, resulting in a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 117.0
The remainder is 35 after subtracting 273 from 308.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 39

Let's proceed to step 5:
The number 39 fits into 354 9 times, leaving a remainder of 3.
The next digit of our result is 9. 
Result so far: 1179.0
Deduct 351 from 354 and we're left 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 6:
The number 39 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 1179.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
39 goes into 300 7 times with a remainder of 27.
The next digit of our result is 7. 
Result so far: 1179.07
If we subtract 273 from 300, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 8:
If we divide 270 by 39, we get 6 and a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 1179.076
Subtracting 234 from 270 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
39 goes into 360 9 times with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 1179.0769
Subtract 351 from 360 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
If we divide 90 by 39, we get 2 and a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 1179.07692
If we subtract 78 from 90, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
The number 39 fits into 120 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 1179.076923
Subtracting 117 from 120 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.

On to step 12:
The number 39 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 1179.076923
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
When dividing 300 by 39, we get 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 1179.07692307
If we subtract 273 from 300, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Our division results in 1179.07692307 with a remaining 2.7e-08.
