We're dividing 545400 by 39 
We want to figure out the number of times 545400 can be divided by 39.

Let's proceed to step 1:
5 divided by 39 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 39

On to step 2:
39 can be fit into 54 1 times, resulting in a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 39 from 54, we get 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 39

Let's proceed to step 3:
39 can be fit into 155 3 times, resulting in a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 117 from 155 and we're left with 38.
Include the next digit (4) from the dividend after 38, then repeat: 384 / 39

Let's proceed to step 4:
When dividing 384 by 39, we get 9 with a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 139.0
Subtract 351 from 384 to get 33.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 39

On to step 5:
39 goes into 330 8 times with a remainder of 18.
The next digit of our result is 8. 
Result so far: 1398.0
Subtracting 312 from 330 leaves us with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 39

Advancing to step 6:
39 can be fit into 180 4 times, resulting in a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 13984.0
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
39 goes into 240 6 times with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 13984.6
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
60 divided by 39 is 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 13984.61
Deduct 39 from 60 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 9:
39 can be fit into 210 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 13984.615
Subtract 195 from 210 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
If we divide 150 by 39, we get 3 and a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 13984.6153
If we take 117 away from 150, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 11:
330 divided by 39 is 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 13984.61538
If we take 312 away from 330, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
When dividing 180 by 39, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 13984.615384
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 13:
39 can be fit into 240 6 times, resulting in a remainder of 6.
The next digit of our result is 6. 
Result so far: 13984.6153846
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
39 can be fit into 60 1 times, resulting in a remainder of 21.
The next digit of our result is 1. 
Result so far: 13984.61538461
Subtracting 39 from 60 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 13984.61538461 and a remainder of 2.1e-08.
