603231 ÷ 39 
Our goal is to divide 603231 by 39.

Going ahead to step 1:
39 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 39

Step 2:
The number 39 fits into 60 1 times, leaving a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 21 after subtracting 39 from 60.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 39

Let's proceed to step 3:
If we divide 213 by 39, we get 5 and a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 195 from 213 to get 18.
Take the next digit (2) from the dividend and append it to 18, then repeat: 182 / 39

Step 4:
If we divide 182 by 39, we get 4 and a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 154.0
Deduct 156 from 182 and we're left with 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 39

Going ahead to step 5:
If we divide 263 by 39, we get 6 and a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 1546.0
Deduct 234 from 263 and we're left with 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 39

Let's proceed to step 6:
When dividing 291 by 39, we get 7 with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 15467.0
Subtracting 273 from 291 leaves us 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 7:
39 can be fit into 180 4 times, resulting in a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 15467.4
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
When dividing 240 by 39, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 15467.46
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.

Step 9:
If we divide 60 by 39, we get 1 and a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 15467.461
The remainder is 21 after subtracting 39 from 60.
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 10:
When dividing 210 by 39, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 15467.4615
The remainder is 15 after subtracting 195 from 210.
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 11:
If we divide 150 by 39, we get 3 and a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 15467.46153
If we subtract 117 from 150, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 12:
39 can be fit into 330 8 times, resulting in a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 15467.461538
Subtracting 312 from 330 leaves us 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.

Let's proceed to step 13:
180 divided by 39 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 15467.4615384
If we take 156 away from 180, we end up 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.

Moving on to step 14:
When dividing 240 by 39, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 15467.46153846
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 15467.46153846, and the remainder is 6e-09.
