481691 ÷ 39 
Our goal is to divide 481691 by 39.

Let's proceed to step 1:
4 divided by 39 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 39

Moving on to step 2:
When dividing 48 by 39, we get 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 39 from 48, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 39

Moving on to step 3:
91 divided by 39 is 2 with a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 78 away from 91, we end up with 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 39

Let's proceed to step 4:
The number 39 fits into 136 3 times, leaving a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
If we subtract 117 from 136, we get 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 39

Advancing to step 5:
39 goes into 199 5 times with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 1235.0
Subtract 195 from 199 to get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 39

Let's proceed to step 6:
41 divided by 39 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 12351.0
Deduct 39 from 41 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
39 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 12351.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
When dividing 200 by 39, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 12351.05
If we subtract 195 from 200, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
If we divide 50 by 39, we get 1 and a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 12351.051
If we take 39 away from 50, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 10:
The number 39 fits into 110 2 times, leaving a remainder of 32.
The next digit of our result is 2. 
Result so far: 12351.0512
If we subtract 78 from 110, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
When dividing 320 by 39, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 12351.05128
If we take 312 away from 320, we end up 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.

Step 12:
If we divide 80 by 39, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 12351.051282
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
39 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 12351.051282
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
The number 39 fits into 200 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 12351.05128205
The remainder is 5 after subtracting 195 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 12351.05128205, with a leftover of 5e-09.
