Let's divide 73865980 by 478
Our goal is to divide 73865980 by 478.

Step 1:
478 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 478

Let's proceed to step 2:
If we divide 73 by 478, we get 0 and a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Include the next digit (8) from the dividend after 73, then repeat: 738 / 478

Advancing to step 3:
478 goes into 738 1 times with a remainder of 260.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 478 away from 738, we end up with 260.
Bring next digit (6) of the dividend behind the 260 and repeat the process: 2606 / 478

Going ahead to step 4:
478 can be fit into 2606 5 times, resulting in a remainder of 216.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 2390 from 2606 leaves us with 216.
Take the next digit (5) from the dividend and append it to 216, then repeat: 2165 / 478

Advancing to step 5:
478 can be fit into 2165 4 times, resulting in a remainder of 253.
Use 4 as the next digit of our solution. 
Result so far: 154.0
Deduct 1912 from 2165 and we're left with 253.
Include the next digit (9) from the dividend after 253, then repeat: 2539 / 478

On to step 6:
2539 divided by 478 is 5 with a remainder of 149.
Put 5 as the next digit of the answer. 
Result so far: 1545.0
Subtract 2390 from 2539 to get 149.
Grab the next digit (8) from the dividend, add it to 149, then carry on: 1498 / 478

Let's proceed to step 7:
When dividing 1498 by 478, we get 3 with a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 15453.0
If we subtract 1434 from 1498, we get 64.
Append the next digit (0) from the dividend to 64 and continue with: 640 / 478

Going ahead to step 8:
The number 478 fits into 640 1 times, leaving a remainder of 162.
Put 1 as the next digit of the answer. 
Result so far: 154531.0
The remainder is 162 after subtracting 478 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 9:
478 can be fit into 1620 3 times, resulting in a remainder of 186.
Use 3 as the next digit of our solution. 
Result so far: 154531.3
If we subtract 1434 from 1620, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 10:
When dividing 1860 by 478, we get 3 with a remainder of 426.
The next digit of our result is 3. 
Result so far: 154531.33
The remainder is 426 after subtracting 1434 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

The quotient of the division is 154531.33, and the remainder is 0.426.
