18866402 ÷ 596 
Let's see how many times 596 fits into 18866402.

Step 1:
596 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 596

On to step 2:
If we divide 18 by 596, we get 0 and a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 596

Let's proceed to step 3:
When dividing 188 by 596, we get 0 with a remainder of 188.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 188 after subtracting 0 from 188.
Include the next digit (6) from the dividend after 188, then repeat: 1886 / 596

Advancing to step 4:
1886 divided by 596 is 3 with a remainder of 98.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 1788 from 1886 and we're left with 98.
Fetch the next digit (6) from the dividend, attach it to 98 and continue: 986 / 596

On to step 5:
986 divided by 596 is 1 with a remainder of 390.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtract 596 from 986 to get 390.
Include the next digit (4) from the dividend after 390, then repeat: 3904 / 596

Advancing to step 6:
The number 596 fits into 3904 6 times, leaving a remainder of 328.
Write down 6 as next digit of the result. 
Result so far: 316.0
The remainder is 328 after subtracting 3576 from 3904.
Fetch the next digit (0) from the dividend, attach it to 328 and continue: 3280 / 596

On to step 7:
If we divide 3280 by 596, we get 5 and a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 3165.0
If we take 2980 away from 3280, we end up with 300.
Append the next digit (2) from the dividend to 300 and continue with: 3002 / 596

Advancing to step 8:
596 can be fit into 3002 5 times, resulting in a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 31655.0
Subtracting 2980 from 3002 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
When dividing 220 by 596, we get 0 with a remainder of 220.
The next digit of our result is 0. 
Result so far: 31655.0
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 10:
The number 596 fits into 2200 3 times, leaving a remainder of 412.
Record the quotient 3 as the next digit in the result. 
Result so far: 31655.03
If we subtract 1788 from 2200, we get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Step 11:
596 can be fit into 4120 6 times, resulting in a remainder of 544.
Use 6 as the next digit of our solution. 
Result so far: 31655.036
The remainder is 544 after subtracting 3576 from 4120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Step 12:
When dividing 5440 by 596, we get 9 with a remainder of 76.
Use 9 as the next digit of our solution. 
Result so far: 31655.0369
If we subtract 5364 from 5440, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 13:
The number 596 fits into 760 1 times, leaving a remainder of 164.
Put 1 as the next digit of the answer. 
Result so far: 31655.03691
Deduct 596 from 760 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 14:
When dividing 1640 by 596, we get 2 with a remainder of 448.
Use 2 as the next digit of our solution. 
Result so far: 31655.036912
Deduct 1192 from 1640 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 15:
If we divide 4480 by 596, we get 7 and a remainder of 308.
The number 7 becomes the next digit in our result. 
Result so far: 31655.0369127
If we take 4172 away from 4480, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 16:
If we divide 3080 by 596, we get 5 and a remainder of 100.
The next digit of our result is 5. 
Result so far: 31655.03691275
Subtract 2980 from 3080 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

In conclusion, the division gives 31655.03691275 with a balance of 1e-07.
