We divide 77478 by 39
We want to divide 77478 by 39.

Advancing to step 1:
The number 39 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 39

Moving on to step 2:
39 can be fit into 77 1 times, resulting in a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 39 from 77 to get 38.
Grab the next digit (4) from the dividend, add it to 38, then carry on: 384 / 39

Moving on to step 3:
39 goes into 384 9 times with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 351 from 384 to get 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 39

Advancing to step 4:
If we divide 337 by 39, we get 8 and a remainder of 25.
Use 8 as the next digit of our solution. 
Result so far: 198.0
Subtracting 312 from 337 leaves us with 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 39

Step 5:
39 can be fit into 258 6 times, resulting in a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 1986.0
If we subtract 234 from 258, 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.

Moving on to step 6:
The number 39 fits into 240 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 1986.6
Subtract 234 from 240 to 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 7:
39 goes into 60 1 times with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1986.61
Subtract 39 from 60 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 8:
39 goes into 210 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 1986.615
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.

On to step 9:
If we divide 150 by 39, we get 3 and a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 1986.6153
Deduct 117 from 150 and we're left 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.

Moving on to step 10:
330 divided by 39 is 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 1986.61538
If we subtract 312 from 330, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
39 goes into 180 4 times with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 1986.615384
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.

Advancing to step 12:
39 can be fit into 240 6 times, resulting in a remainder of 6.
The next digit of our result is 6. 
Result so far: 1986.6153846
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.

Going ahead to step 13:
If we divide 60 by 39, we get 1 and a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1986.61538461
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.

The final result is 1986.61538461 with a remainder of 2.1e-08.
