79538263 ÷ 439 
We want to figure out the number of times 79538263 can be divided by 439.

Moving on to step 1:
If we divide 7 by 439, we get 0 and 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.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 439

Step 2:
When dividing 79 by 439, we get 0 with a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Bring next digit (5) of the dividend behind the 79 and repeat the process: 795 / 439

Advancing to step 3:
439 goes into 795 1 times with a remainder of 356.
The next digit of our result is 1. 
Result so far: 1.0
If we take 439 away from 795, we end up with 356.
Grab the next digit (3) from the dividend, add it to 356, then carry on: 3563 / 439

Going ahead to step 4:
When dividing 3563 by 439, we get 8 with a remainder of 51.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 3512 from 3563, we get 51.
Take the next digit (8) from the dividend and append it to 51, then repeat: 518 / 439

Let's proceed to step 5:
When dividing 518 by 439, we get 1 with a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 181.0
Deduct 439 from 518 and we're left with 79.
Append the next digit (2) from the dividend to 79 and continue with: 792 / 439

Going ahead to step 6:
439 goes into 792 1 times with a remainder of 353.
Put 1 as the next digit of the answer. 
Result so far: 1811.0
Subtracting 439 from 792 leaves us with 353.
Bring next digit (6) of the dividend behind the 353 and repeat the process: 3536 / 439

Going ahead to step 7:
The number 439 fits into 3536 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 18118.0
If we take 3512 away from 3536, we end up with 24.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 439

Going ahead to step 8:
439 goes into 243 0 times with a remainder of 243.
Write down 0 as next digit of the result. 
Result so far: 181180.0
Subtract 0 from 243 to get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Step 9:
When dividing 2430 by 439, we get 5 with a remainder of 235.
The number 5 becomes the next digit in our result. 
Result so far: 181180.5
Subtract 2195 from 2430 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Moving on to step 10:
2350 divided by 439 is 5 with a remainder of 155.
Use 5 as the next digit of our solution. 
Result so far: 181180.55
Subtracting 2195 from 2350 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Our division results in 181180.55 with a remaining 0.155.
