86304621 divided by 474 
Our goal is to divide 86304621 by 474.

Step 1:
When dividing 8 by 474, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 474

Going ahead to step 2:
If we divide 86 by 474, we get 0 and a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Bring next digit (3) of the dividend behind the 86 and repeat the process: 863 / 474

Advancing to step 3:
If we divide 863 by 474, we get 1 and a remainder of 389.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 474 from 863 leaves us with 389.
Bring next digit (0) of the dividend behind the 389 and repeat the process: 3890 / 474

Advancing to step 4:
If we divide 3890 by 474, we get 8 and a remainder of 98.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we take 3792 away from 3890, we end up with 98.
Append the next digit (4) from the dividend to 98 and continue with: 984 / 474

On to step 5:
984 divided by 474 is 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 182.0
Subtract 948 from 984 to get 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 474

Going ahead to step 6:
The number 474 fits into 366 0 times, leaving a remainder of 366.
Record the quotient 0 as the next digit in the result. 
Result so far: 1820.0
The remainder is 366 after subtracting 0 from 366.
Append the next digit (2) from the dividend to 366 and continue with: 3662 / 474

Step 7:
474 can be fit into 3662 7 times, resulting in a remainder of 344.
The number 7 becomes the next digit in our result. 
Result so far: 18207.0
The remainder is 344 after subtracting 3318 from 3662.
Fetch the next digit (1) from the dividend, attach it to 344 and continue: 3441 / 474

Step 8:
When dividing 3441 by 474, we get 7 with a remainder of 123.
Put 7 as the next digit of the answer. 
Result so far: 182077.0
Subtract 3318 from 3441 to get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Advancing to step 9:
1230 divided by 474 is 2 with a remainder of 282.
The number 2 becomes the next digit in our result. 
Result so far: 182077.2
If we subtract 948 from 1230, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 10:
2820 divided by 474 is 5 with a remainder of 450.
Use 5 as the next digit of our solution. 
Result so far: 182077.25
Subtract 2370 from 2820 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 11:
If we divide 4500 by 474, we get 9 and a remainder of 234.
Use 9 as the next digit of our solution. 
Result so far: 182077.259
Subtracting 4266 from 4500 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Let's proceed to step 12:
If we divide 2340 by 474, we get 4 and a remainder of 444.
Write down 4 as next digit of the result. 
Result so far: 182077.2594
Deduct 1896 from 2340 and we're left with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

On to step 13:
The number 474 fits into 4440 9 times, leaving a remainder of 174.
The number 9 becomes the next digit in our result. 
Result so far: 182077.25949
Subtracting 4266 from 4440 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 14:
If we divide 1740 by 474, we get 3 and a remainder of 318.
Write down 3 as next digit of the result. 
Result so far: 182077.259493
Deduct 1422 from 1740 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Moving on to step 15:
474 goes into 3180 6 times with a remainder of 336.
Put 6 as the next digit of the answer. 
Result so far: 182077.2594936
Subtract 2844 from 3180 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 16:
When dividing 3360 by 474, we get 7 with a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 182077.25949367
The remainder is 42 after subtracting 3318 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 182077.25949367 and a remainder of 4.2e-08.
