We divide 771858 by 39
We want to divide 771858 by 39.

Step 1:
7 divided by 39 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 39

Advancing to step 2:
If we divide 77 by 39, we get 1 and a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 39 from 77 leaves us with 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 39

Let's proceed to step 3:
The number 39 fits into 381 9 times, leaving a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we subtract 351 from 381, we get 30.
Grab the next digit (8) from the dividend, add it to 30, then carry on: 308 / 39

On to step 4:
When dividing 308 by 39, we get 7 with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 197.0
If we take 273 away from 308, we end up with 35.
Take the next digit (5) from the dividend and append it to 35, then repeat: 355 / 39

Moving on to step 5:
39 goes into 355 9 times with a remainder of 4.
The next digit of our result is 9. 
Result so far: 1979.0
If we take 351 away from 355, we end up with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 39

Moving on to step 6:
When dividing 48 by 39, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 19791.0
If we take 39 away from 48, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
If we divide 90 by 39, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 19791.2
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
The number 39 fits into 120 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 19791.23
Deduct 117 from 120 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
39 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 19791.23
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
The number 39 fits into 300 7 times, leaving a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 19791.2307
Deduct 273 from 300 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 11:
The number 39 fits into 270 6 times, leaving a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 19791.23076
The remainder is 36 after subtracting 234 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
39 goes into 360 9 times with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 19791.230769
Deduct 351 from 360 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 13:
If we divide 90 by 39, we get 2 and a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 19791.2307692
If we subtract 78 from 90, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
The number 39 fits into 120 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 19791.23076923
Subtract 117 from 120 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 19791.23076923 and a remainder of 3e-09.
