We look at the division of 43869923 by 599 
Our goal is to divide 43869923 by 599.

Moving on to step 1:
599 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
Deduct 0 from 4 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 599

Going ahead to step 2:
If we divide 43 by 599, we get 0 and a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 599

On to step 3:
599 can be fit into 438 0 times, resulting in a remainder of 438.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 438 to get 438.
Bring next digit (6) of the dividend behind the 438 and repeat the process: 4386 / 599

Moving on to step 4:
599 goes into 4386 7 times with a remainder of 193.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 4193 from 4386, we get 193.
Take the next digit (9) from the dividend and append it to 193, then repeat: 1939 / 599

Advancing to step 5:
599 can be fit into 1939 3 times, resulting in a remainder of 142.
Use 3 as the next digit of our solution. 
Result so far: 73.0
If we take 1797 away from 1939, we end up with 142.
Bring next digit (9) of the dividend behind the 142 and repeat the process: 1429 / 599

On to step 6:
The number 599 fits into 1429 2 times, leaving a remainder of 231.
Write down 2 as next digit of the result. 
Result so far: 732.0
If we subtract 1198 from 1429, we get 231.
Take the next digit (2) from the dividend and append it to 231, then repeat: 2312 / 599

On to step 7:
When dividing 2312 by 599, we get 3 with a remainder of 515.
Write down 3 as next digit of the result. 
Result so far: 7323.0
Subtract 1797 from 2312 to get 515.
Include the next digit (3) from the dividend after 515, then repeat: 5153 / 599

Moving on to step 8:
The number 599 fits into 5153 8 times, leaving a remainder of 361.
Put 8 as the next digit of the answer. 
Result so far: 73238.0
The remainder is 361 after subtracting 4792 from 5153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

On to step 9:
599 goes into 3610 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 73238.6
If we subtract 3594 from 3610, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
160 divided by 599 is 0 with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 73238.6
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 11:
When dividing 1600 by 599, we get 2 with a remainder of 402.
The next digit of our result is 2. 
Result so far: 73238.602
Subtract 1198 from 1600 to get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Advancing to step 12:
When dividing 4020 by 599, we get 6 with a remainder of 426.
Use 6 as the next digit of our solution. 
Result so far: 73238.6026
The remainder is 426 after subtracting 3594 from 4020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

On to step 13:
If we divide 4260 by 599, we get 7 and a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 73238.60267
Subtract 4193 from 4260 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 14:
599 goes into 670 1 times with a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 73238.602671
Subtract 599 from 670 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 15:
If we divide 710 by 599, we get 1 and a remainder of 111.
The number 1 becomes the next digit in our result. 
Result so far: 73238.6026711
If we take 599 away from 710, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

After the division, we end up with 73238.6026711 and a remainder of 1.11e-06.
