Let's divide 76801421 by 320
Let's see how many times 320 fits into 76801421.

Let's proceed to step 1:
When dividing 7 by 320, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 320

Moving on to step 2:
320 can be fit into 76 0 times, resulting in a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Append the next digit (8) from the dividend to 76 and continue with: 768 / 320

Moving on to step 3:
768 divided by 320 is 2 with a remainder of 128.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 640 from 768, we get 128.
Fetch the next digit (0) from the dividend, attach it to 128 and continue: 1280 / 320

Moving on to step 4:
When dividing 1280 by 320, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 24.0
Subtract 1280 from 1280 to get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 320

On to step 5:
320 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 240.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 320

Let's proceed to step 6:
14 divided by 320 is 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 2400.0
Deduct 0 from 14 and we're left with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 320

Going ahead to step 7:
When dividing 142 by 320, we get 0 with a remainder of 142.
Use 0 as the next digit of our solution. 
Result so far: 24000.0
If we subtract 0 from 142, we get 142.
Grab the next digit (1) from the dividend, add it to 142, then carry on: 1421 / 320

Moving on to step 8:
The number 320 fits into 1421 4 times, leaving a remainder of 141.
Put 4 as the next digit of the answer. 
Result so far: 240004.0
Deduct 1280 from 1421 and we're left with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 9:
320 can be fit into 1410 4 times, resulting in a remainder of 130.
Write down 4 as next digit of the result. 
Result so far: 240004.4
The remainder is 130 after subtracting 1280 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
320 goes into 1300 4 times with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 240004.44
If we take 1280 away from 1300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 240004.44 with a remainder of 0.02.
