86239336 ÷ 199 
Our goal is to divide 86239336 by 199.

Step 1:
The number 199 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 199

Moving on to step 2:
When dividing 86 by 199, we get 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Take the next digit (2) from the dividend and append it to 86, then repeat: 862 / 199

Let's proceed to step 3:
199 can be fit into 862 4 times, resulting in a remainder of 66.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 66 after subtracting 796 from 862.
Append the next digit (3) from the dividend to 66 and continue with: 663 / 199

Advancing to step 4:
When dividing 663 by 199, we get 3 with a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtract 597 from 663 to get 66.
Append the next digit (9) from the dividend to 66 and continue with: 669 / 199

Advancing to step 5:
199 goes into 669 3 times with a remainder of 72.
Record the quotient 3 as the next digit in the result. 
Result so far: 433.0
The remainder is 72 after subtracting 597 from 669.
Fetch the next digit (3) from the dividend, attach it to 72 and continue: 723 / 199

Moving on to step 6:
199 can be fit into 723 3 times, resulting in a remainder of 126.
Use 3 as the next digit of our solution. 
Result so far: 4333.0
The remainder is 126 after subtracting 597 from 723.
Append the next digit (3) from the dividend to 126 and continue with: 1263 / 199

Step 7:
When dividing 1263 by 199, we get 6 with a remainder of 69.
Record the quotient 6 as the next digit in the result. 
Result so far: 43336.0
Subtract 1194 from 1263 to get 69.
Grab the next digit (6) from the dividend, add it to 69, then carry on: 696 / 199

Let's proceed to step 8:
199 goes into 696 3 times with a remainder of 99.
The next digit of our result is 3. 
Result so far: 433363.0
If we take 597 away from 696, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Let's proceed to step 9:
990 divided by 199 is 4 with a remainder of 194.
Put 4 as the next digit of the answer. 
Result so far: 433363.4
If we take 796 away from 990, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Step 10:
199 goes into 1940 9 times with a remainder of 149.
Use 9 as the next digit of our solution. 
Result so far: 433363.49
Subtracting 1791 from 1940 leaves us with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

On to step 11:
If we divide 1490 by 199, we get 7 and a remainder of 97.
Use 7 as the next digit of our solution. 
Result so far: 433363.497
Subtracting 1393 from 1490 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 12:
199 can be fit into 970 4 times, resulting in a remainder of 174.
The next digit of our result is 4. 
Result so far: 433363.4974
If we subtract 796 from 970, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 13:
The number 199 fits into 1740 8 times, leaving a remainder of 148.
The number 8 becomes the next digit in our result. 
Result so far: 433363.49748
Deduct 1592 from 1740 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 14:
1480 divided by 199 is 7 with a remainder of 87.
Put 7 as the next digit of the answer. 
Result so far: 433363.497487
Subtracting 1393 from 1480 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 15:
199 can be fit into 870 4 times, resulting in a remainder of 74.
Use 4 as the next digit of our solution. 
Result so far: 433363.4974874
If we take 796 away from 870, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 16:
199 can be fit into 740 3 times, resulting in a remainder of 143.
The next digit of our result is 3. 
Result so far: 433363.49748743
Subtract 597 from 740 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

The final result is 433363.49748743 with a remainder of 1.43e-07.
