38154439 ÷ 879 
We want to figure out the number of times 38154439 can be divided by 879.

Advancing to step 1:
879 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 879

Advancing to step 2:
When dividing 38 by 879, we get 0 with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Grab the next digit (1) from the dividend, add it to 38, then carry on: 381 / 879

Advancing to step 3:
The number 879 fits into 381 0 times, leaving a remainder of 381.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 381 to get 381.
Take the next digit (5) from the dividend and append it to 381, then repeat: 3815 / 879

Let's proceed to step 4:
879 can be fit into 3815 4 times, resulting in a remainder of 299.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 3516 from 3815 to get 299.
Append the next digit (4) from the dividend to 299 and continue with: 2994 / 879

Going ahead to step 5:
2994 divided by 879 is 3 with a remainder of 357.
The next digit of our result is 3. 
Result so far: 43.0
The remainder is 357 after subtracting 2637 from 2994.
Append the next digit (4) from the dividend to 357 and continue with: 3574 / 879

On to step 6:
The number 879 fits into 3574 4 times, leaving a remainder of 58.
The next digit of our result is 4. 
Result so far: 434.0
Deduct 3516 from 3574 and we're left with 58.
Append the next digit (3) from the dividend to 58 and continue with: 583 / 879

Moving on to step 7:
879 goes into 583 0 times with a remainder of 583.
Use 0 as the next digit of our solution. 
Result so far: 4340.0
If we take 0 away from 583, we end up with 583.
Grab the next digit (9) from the dividend, add it to 583, then carry on: 5839 / 879

Let's proceed to step 8:
The number 879 fits into 5839 6 times, leaving a remainder of 565.
Record the quotient 6 as the next digit in the result. 
Result so far: 43406.0
Deduct 5274 from 5839 and we're left with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Going ahead to step 9:
When dividing 5650 by 879, we get 6 with a remainder of 376.
Use 6 as the next digit of our solution. 
Result so far: 43406.6
Deduct 5274 from 5650 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 10:
If we divide 3760 by 879, we get 4 and a remainder of 244.
Use 4 as the next digit of our solution. 
Result so far: 43406.64
Deduct 3516 from 3760 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Going ahead to step 11:
2440 divided by 879 is 2 with a remainder of 682.
Put 2 as the next digit of the answer. 
Result so far: 43406.642
If we take 1758 away from 2440, we end up with 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Step 12:
879 can be fit into 6820 7 times, resulting in a remainder of 667.
The number 7 becomes the next digit in our result. 
Result so far: 43406.6427
Subtract 6153 from 6820 to get 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

Step 13:
6670 divided by 879 is 7 with a remainder of 517.
The number 7 becomes the next digit in our result. 
Result so far: 43406.64277
Subtract 6153 from 6670 to get 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

After the division, we end up with 43406.64277 and a remainder of 0.000517.
