40039189 ÷ 599 
Our goal is to divide 40039189 by 599.

Going ahead to step 1:
599 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 599

Moving on to step 2:
599 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Fetch the next digit (0) from the dividend, attach it to 40 and continue: 400 / 599

Step 3:
The number 599 fits into 400 0 times, leaving a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 400 to get 400.
Bring next digit (3) of the dividend behind the 400 and repeat the process: 4003 / 599

On to step 4:
If we divide 4003 by 599, we get 6 and a remainder of 409.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 3594 from 4003 to get 409.
Append the next digit (9) from the dividend to 409 and continue with: 4099 / 599

On to step 5:
599 goes into 4099 6 times with a remainder of 505.
The next digit of our result is 6. 
Result so far: 66.0
Subtract 3594 from 4099 to get 505.
Include the next digit (1) from the dividend after 505, then repeat: 5051 / 599

Let's proceed to step 6:
599 goes into 5051 8 times with a remainder of 259.
Write down 8 as next digit of the result. 
Result so far: 668.0
If we subtract 4792 from 5051, we get 259.
Grab the next digit (8) from the dividend, add it to 259, then carry on: 2598 / 599

Going ahead to step 7:
When dividing 2598 by 599, we get 4 with a remainder of 202.
Use 4 as the next digit of our solution. 
Result so far: 6684.0
If we subtract 2396 from 2598, we get 202.
Append the next digit (9) from the dividend to 202 and continue with: 2029 / 599

Moving on to step 8:
The number 599 fits into 2029 3 times, leaving a remainder of 232.
Put 3 as the next digit of the answer. 
Result so far: 66843.0
Deduct 1797 from 2029 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 9:
The number 599 fits into 2320 3 times, leaving a remainder of 523.
Record the quotient 3 as the next digit in the result. 
Result so far: 66843.3
The remainder is 523 after subtracting 1797 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Let's proceed to step 10:
If we divide 5230 by 599, we get 8 and a remainder of 438.
Use 8 as the next digit of our solution. 
Result so far: 66843.38
If we subtract 4792 from 5230, we get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Let's proceed to step 11:
The number 599 fits into 4380 7 times, leaving a remainder of 187.
Use 7 as the next digit of our solution. 
Result so far: 66843.387
If we take 4193 away from 4380, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Moving on to step 12:
When dividing 1870 by 599, we get 3 with a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 66843.3873
If we subtract 1797 from 1870, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 13:
730 divided by 599 is 1 with a remainder of 131.
Write down 1 as next digit of the result. 
Result so far: 66843.38731
Subtract 599 from 730 to get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 14:
The number 599 fits into 1310 2 times, leaving a remainder of 112.
Use 2 as the next digit of our solution. 
Result so far: 66843.387312
If we take 1198 away from 1310, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 15:
599 can be fit into 1120 1 times, resulting in a remainder of 521.
Use 1 as the next digit of our solution. 
Result so far: 66843.3873121
The remainder is 521 after subtracting 599 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

Moving on to step 16:
599 can be fit into 5210 8 times, resulting in a remainder of 418.
Use 8 as the next digit of our solution. 
Result so far: 66843.38731218
If we subtract 4792 from 5210, we get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

After the division, we end up with 66843.38731218 and a remainder of 4.18e-07.
