879390 ÷ 39 
We want to figure out the number of times 879390 can be divided by 39.

Moving on to step 1:
39 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 39

On to step 2:
The number 39 fits into 87 2 times, leaving a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 78 from 87 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 39

Let's proceed to step 3:
When dividing 99 by 39, we get 2 with a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we subtract 78 from 99, we get 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 39

Advancing to step 4:
When dividing 213 by 39, we get 5 with a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 225.0
If we take 195 away from 213, we end up with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 39

Let's proceed to step 5:
If we divide 189 by 39, we get 4 and a remainder of 33.
Put 4 as the next digit of the answer. 
Result so far: 2254.0
Subtract 156 from 189 to get 33.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 39

Step 6:
If we divide 330 by 39, we get 8 and a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 22548.0
Subtract 312 from 330 to 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.

Going ahead to step 7:
39 goes into 180 4 times with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 22548.4
Subtract 156 from 180 to 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.

Let's proceed to step 8:
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: 22548.46
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.

Advancing to step 9:
39 goes into 60 1 times with a remainder of 21.
The next digit of our result is 1. 
Result so far: 22548.461
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.

Moving on to step 10:
When dividing 210 by 39, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 22548.4615
Deduct 195 from 210 and we're left 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.

Let's proceed to step 11:
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: 22548.46153
Subtracting 117 from 150 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.

Step 12:
330 divided by 39 is 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 22548.461538
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 13:
39 goes into 180 4 times with a remainder of 24.
The next digit of our result is 4. 
Result so far: 22548.4615384
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.

Let's proceed to step 14:
39 goes into 240 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 22548.46153846
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.

After the division, we end up with 22548.46153846 and a remainder of 6e-09.
