We're dividing 78470448 by 921 
We're looking to find how many times 921 goes into 78470448.

Moving on to step 1:
When dividing 7 by 921, we get 0 with 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 (8) from the dividend to 7 and continue with: 78 / 921

Let's proceed to step 2:
When dividing 78 by 921, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 921

Step 3:
784 divided by 921 is 0 with a remainder of 784.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 784 after subtracting 0 from 784.
Append the next digit (7) from the dividend to 784 and continue with: 7847 / 921

Let's proceed to step 4:
921 goes into 7847 8 times with a remainder of 479.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 7368 from 7847 and we're left with 479.
Include the next digit (0) from the dividend after 479, then repeat: 4790 / 921

Let's proceed to step 5:
If we divide 4790 by 921, we get 5 and a remainder of 185.
Write down 5 as next digit of the result. 
Result so far: 85.0
Deduct 4605 from 4790 and we're left with 185.
Take the next digit (4) from the dividend and append it to 185, then repeat: 1854 / 921

Advancing to step 6:
When dividing 1854 by 921, we get 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 852.0
Deduct 1842 from 1854 and we're left with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 921

On to step 7:
921 goes into 124 0 times with a remainder of 124.
Record the quotient 0 as the next digit in the result. 
Result so far: 8520.0
If we take 0 away from 124, we end up with 124.
Take the next digit (8) from the dividend and append it to 124, then repeat: 1248 / 921

On to step 8:
When dividing 1248 by 921, we get 1 with a remainder of 327.
Write down 1 as next digit of the result. 
Result so far: 85201.0
If we subtract 921 from 1248, we get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Step 9:
When dividing 3270 by 921, we get 3 with a remainder of 507.
Put 3 as the next digit of the answer. 
Result so far: 85201.3
The remainder is 507 after subtracting 2763 from 3270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Going ahead to step 10:
When dividing 5070 by 921, we get 5 with a remainder of 465.
Use 5 as the next digit of our solution. 
Result so far: 85201.35
Subtracting 4605 from 5070 leaves us with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Advancing to step 11:
If we divide 4650 by 921, we get 5 and a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 85201.355
Subtract 4605 from 4650 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 85201.355 with a remainder of 0.0045.
