763263 ÷ 39 
Our goal is to divide 763263 by 39.

Let's proceed to step 1:
The number 39 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 39

Moving on to step 2:
39 can be fit into 76 1 times, resulting in a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 39 from 76 leaves us with 37.
Append the next digit (3) from the dividend to 37 and continue with: 373 / 39

Step 3:
The number 39 fits into 373 9 times, leaving a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtracting 351 from 373 leaves us with 22.
Bring next digit (2) of the dividend behind the 22 and repeat the process: 222 / 39

Advancing to step 4:
39 goes into 222 5 times with a remainder of 27.
Use 5 as the next digit of our solution. 
Result so far: 195.0
Deduct 195 from 222 and we're left with 27.
Take the next digit (6) from the dividend and append it to 27, then repeat: 276 / 39

Advancing to step 5:
39 can be fit into 276 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 1957.0
The remainder is 3 after subtracting 273 from 276.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 39

Moving on to step 6:
33 divided by 39 is 0 with a remainder of 33.
The next digit of our result is 0. 
Result so far: 19570.0
Subtracting 0 from 33 leaves us 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.

Let's proceed to step 7:
If we divide 330 by 39, we get 8 and a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 19570.8
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.

Going ahead to step 8:
180 divided by 39 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 19570.84
Subtracting 156 from 180 leaves us 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.

Let's proceed to step 9:
If we divide 240 by 39, we get 6 and a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 19570.846
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.

Going ahead to step 10:
60 divided by 39 is 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 19570.8461
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.

Advancing to step 11:
39 can be fit into 210 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 19570.84615
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 12:
150 divided by 39 is 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 19570.846153
The remainder is 33 after subtracting 117 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 13:
39 goes into 330 8 times with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 19570.8461538
The remainder is 18 after subtracting 312 from 330.
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 14:
39 can be fit into 180 4 times, resulting in a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 19570.84615384
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 19570.84615384, with a leftover of 2.4e-08.
