Let's divide 12307903 by 199
Our goal is to divide 12307903 by 199.

Moving on to step 1:
199 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 199

Step 2:
When dividing 12 by 199, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 199

Let's proceed to step 3:
199 can be fit into 123 0 times, resulting in a remainder of 123.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 123, we get 123.
Include the next digit (0) from the dividend after 123, then repeat: 1230 / 199

Step 4:
199 can be fit into 1230 6 times, resulting in a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 1194 from 1230, we get 36.
Bring next digit (7) of the dividend behind the 36 and repeat the process: 367 / 199

On to step 5:
When dividing 367 by 199, we get 1 with a remainder of 168.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Deduct 199 from 367 and we're left with 168.
Append the next digit (9) from the dividend to 168 and continue with: 1689 / 199

Let's proceed to step 6:
199 goes into 1689 8 times with a remainder of 97.
Put 8 as the next digit of the answer. 
Result so far: 618.0
If we take 1592 away from 1689, we end up with 97.
Fetch the next digit (0) from the dividend, attach it to 97 and continue: 970 / 199

Step 7:
The number 199 fits into 970 4 times, leaving a remainder of 174.
Put 4 as the next digit of the answer. 
Result so far: 6184.0
Subtract 796 from 970 to get 174.
Include the next digit (3) from the dividend after 174, then repeat: 1743 / 199

Step 8:
199 can be fit into 1743 8 times, resulting in a remainder of 151.
Record the quotient 8 as the next digit in the result. 
Result so far: 61848.0
Deduct 1592 from 1743 and we're left with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Advancing to step 9:
1510 divided by 199 is 7 with a remainder of 117.
The next digit of our result is 7. 
Result so far: 61848.7
If we take 1393 away from 1510, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 10:
When dividing 1170 by 199, we get 5 with a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 61848.75
Deduct 995 from 1170 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 11:
199 goes into 1750 8 times with a remainder of 158.
Write down 8 as next digit of the result. 
Result so far: 61848.758
Deduct 1592 from 1750 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 12:
199 can be fit into 1580 7 times, resulting in a remainder of 187.
Put 7 as the next digit of the answer. 
Result so far: 61848.7587
If we take 1393 away from 1580, 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.

On to step 13:
The number 199 fits into 1870 9 times, leaving a remainder of 79.
The next digit of our result is 9. 
Result so far: 61848.75879
Deduct 1791 from 1870 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 14:
The number 199 fits into 790 3 times, leaving a remainder of 193.
Put 3 as the next digit of the answer. 
Result so far: 61848.758793
If we take 597 away from 790, we end up with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Let's proceed to step 15:
The number 199 fits into 1930 9 times, leaving a remainder of 139.
Put 9 as the next digit of the answer. 
Result so far: 61848.7587939
Subtracting 1791 from 1930 leaves us with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 16:
When dividing 1390 by 199, we get 6 with a remainder of 196.
The number 6 becomes the next digit in our result. 
Result so far: 61848.75879396
Subtract 1194 from 1390 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

After the division, we end up with 61848.75879396 and a remainder of 1.96e-07.
