Let's divide 769845 by 39
Our goal is to divide 769845 by 39.

Let's proceed to step 1:
When dividing 7 by 39, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 39

Advancing to step 2:
39 goes into 76 1 times with a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 39 away from 76, we end up with 37.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 39

Step 3:
If we divide 379 by 39, we get 9 and a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 351 from 379 leaves us with 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 39

Let's proceed to step 4:
39 can be fit into 288 7 times, resulting in a remainder of 15.
The next digit of our result is 7. 
Result so far: 197.0
If we take 273 away from 288, we end up with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 39

Advancing to step 5:
39 goes into 154 3 times with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 1973.0
If we take 117 away from 154, we end up with 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 39

Going ahead to step 6:
The number 39 fits into 375 9 times, leaving a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 19739.0
Subtracting 351 from 375 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 7:
When dividing 240 by 39, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 19739.6
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.

Going ahead to step 8:
39 can be fit into 60 1 times, resulting in a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 19739.61
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.

Advancing to step 9:
39 can be fit into 210 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 19739.615
Subtracting 195 from 210 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
The number 39 fits into 150 3 times, leaving a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 19739.6153
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.

Going ahead to step 11:
39 goes into 330 8 times with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 19739.61538
Deduct 312 from 330 and we're left 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.

On to step 12:
When dividing 180 by 39, we get 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 19739.615384
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.

Going ahead to step 13:
39 can be fit into 240 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 19739.6153846
Deduct 234 from 240 and we're left 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:
The number 39 fits into 60 1 times, leaving a remainder of 21.
The next digit of our result is 1. 
Result so far: 19739.61538461
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.

After the division, we end up with 19739.61538461 and a remainder of 2.1e-08.
