Let's divide 42406193 by 480
We're looking to find how many times 480 goes into 42406193.

On to step 1:
480 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 480

Step 2:
480 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Grab the next digit (4) from the dividend, add it to 42, then carry on: 424 / 480

On to step 3:
480 can be fit into 424 0 times, resulting in a remainder of 424.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 424 leaves us with 424.
Bring next digit (0) of the dividend behind the 424 and repeat the process: 4240 / 480

Moving on to step 4:
When dividing 4240 by 480, we get 8 with a remainder of 400.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 3840 from 4240 leaves us with 400.
Append the next digit (6) from the dividend to 400 and continue with: 4006 / 480

Moving on to step 5:
When dividing 4006 by 480, we get 8 with a remainder of 166.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
If we take 3840 away from 4006, we end up with 166.
Include the next digit (1) from the dividend after 166, then repeat: 1661 / 480

Advancing to step 6:
If we divide 1661 by 480, we get 3 and a remainder of 221.
Write down 3 as next digit of the result. 
Result so far: 883.0
Subtract 1440 from 1661 to get 221.
Include the next digit (9) from the dividend after 221, then repeat: 2219 / 480

Advancing to step 7:
2219 divided by 480 is 4 with a remainder of 299.
Use 4 as the next digit of our solution. 
Result so far: 8834.0
Subtract 1920 from 2219 to get 299.
Append the next digit (3) from the dividend to 299 and continue with: 2993 / 480

On to step 8:
When dividing 2993 by 480, we get 6 with a remainder of 113.
Record the quotient 6 as the next digit in the result. 
Result so far: 88346.0
If we subtract 2880 from 2993, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 9:
If we divide 1130 by 480, we get 2 and a remainder of 170.
Use 2 as the next digit of our solution. 
Result so far: 88346.2
Subtracting 960 from 1130 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 10:
When dividing 1700 by 480, we get 3 with a remainder of 260.
Use 3 as the next digit of our solution. 
Result so far: 88346.23
If we take 1440 away from 1700, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 11:
When dividing 2600 by 480, we get 5 with a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 88346.235
Subtract 2400 from 2600 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 12:
The number 480 fits into 2000 4 times, leaving a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 88346.2354
If we take 1920 away from 2000, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
If we divide 800 by 480, we get 1 and a remainder of 320.
Record the quotient 1 as the next digit in the result. 
Result so far: 88346.23541
If we subtract 480 from 800, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 14:
480 can be fit into 3200 6 times, resulting in a remainder of 320.
The next digit of our result is 6. 
Result so far: 88346.235416
If we take 2880 away from 3200, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 15:
3200 divided by 480 is 6 with a remainder of 320.
The number 6 becomes the next digit in our result. 
Result so far: 88346.2354166
Subtracting 2880 from 3200 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Our division results in 88346.2354166 with a remaining 3.2e-06.
