78016558 ÷ 475 
Our goal is to divide 78016558 by 475.

Going ahead to step 1:
If we divide 7 by 475, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 475

Advancing to step 2:
78 divided by 475 is 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 475

On to step 3:
When dividing 780 by 475, we get 1 with a remainder of 305.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 475 from 780 to get 305.
Append the next digit (1) from the dividend to 305 and continue with: 3051 / 475

Let's proceed to step 4:
If we divide 3051 by 475, we get 6 and a remainder of 201.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 2850 from 3051 and we're left with 201.
Bring next digit (6) of the dividend behind the 201 and repeat the process: 2016 / 475

Let's proceed to step 5:
If we divide 2016 by 475, we get 4 and a remainder of 116.
Record the quotient 4 as the next digit in the result. 
Result so far: 164.0
Subtract 1900 from 2016 to get 116.
Include the next digit (5) from the dividend after 116, then repeat: 1165 / 475

Advancing to step 6:
475 can be fit into 1165 2 times, resulting in a remainder of 215.
The number 2 becomes the next digit in our result. 
Result so far: 1642.0
If we subtract 950 from 1165, we get 215.
Include the next digit (5) from the dividend after 215, then repeat: 2155 / 475

On to step 7:
475 goes into 2155 4 times with a remainder of 255.
Put 4 as the next digit of the answer. 
Result so far: 16424.0
If we subtract 1900 from 2155, we get 255.
Include the next digit (8) from the dividend after 255, then repeat: 2558 / 475

On to step 8:
If we divide 2558 by 475, we get 5 and a remainder of 183.
The next digit of our result is 5. 
Result so far: 164245.0
If we subtract 2375 from 2558, we get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 9:
1830 divided by 475 is 3 with a remainder of 405.
The next digit of our result is 3. 
Result so far: 164245.3
Subtracting 1425 from 1830 leaves us with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Going ahead to step 10:
The number 475 fits into 4050 8 times, leaving a remainder of 250.
Use 8 as the next digit of our solution. 
Result so far: 164245.38
Subtract 3800 from 4050 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 11:
When dividing 2500 by 475, we get 5 with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 164245.385
The remainder is 125 after subtracting 2375 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 12:
475 can be fit into 1250 2 times, resulting in a remainder of 300.
Use 2 as the next digit of our solution. 
Result so far: 164245.3852
If we take 950 away from 1250, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 13:
475 can be fit into 3000 6 times, resulting in a remainder of 150.
Put 6 as the next digit of the answer. 
Result so far: 164245.38526
The remainder is 150 after subtracting 2850 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 14:
1500 divided by 475 is 3 with a remainder of 75.
The number 3 becomes the next digit in our result. 
Result so far: 164245.385263
If we subtract 1425 from 1500, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 15:
475 can be fit into 750 1 times, resulting in a remainder of 275.
The number 1 becomes the next digit in our result. 
Result so far: 164245.3852631
Subtract 475 from 750 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 16:
If we divide 2750 by 475, we get 5 and a remainder of 375.
Record the quotient 5 as the next digit in the result. 
Result so far: 164245.38526315
The remainder is 375 after subtracting 2375 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

The final result is 164245.38526315 with a remainder of 3.75e-07.
