553946 divided by 39 
Our goal is to divide 553946 by 39.

Let's proceed to step 1:
39 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 39

Going ahead to step 2:
The number 39 fits into 55 1 times, leaving a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 39 away from 55, we end up with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 39

Let's proceed to step 3:
39 goes into 163 4 times with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 7 after subtracting 156 from 163.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 39

Step 4:
39 goes into 79 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 142.0
Deduct 78 from 79 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 39

Let's proceed to step 5:
If we divide 14 by 39, we get 0 and a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 1420.0
If we take 0 away from 14, we end up with 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 39

Advancing to step 6:
When dividing 146 by 39, we get 3 with a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 14203.0
If we take 117 away from 146, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
39 can be fit into 290 7 times, resulting in a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 14203.7
If we subtract 273 from 290, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
39 can be fit into 170 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 14203.74
Deduct 156 from 170 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
If we divide 140 by 39, we get 3 and a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 14203.743
Subtracting 117 from 140 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 10:
39 goes into 230 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 14203.7435
Subtract 195 from 230 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 11:
When dividing 350 by 39, we get 8 with a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 14203.74358
If we subtract 312 from 350, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
39 can be fit into 380 9 times, resulting in a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 14203.743589
The remainder is 29 after subtracting 351 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 13:
290 divided by 39 is 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 14203.7435897
The remainder is 17 after subtracting 273 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 14:
If we divide 170 by 39, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 14203.74358974
Subtracting 156 from 170 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 14203.74358974 and a remainder of 1.4e-08.
