Let's divide 99839787 by 290
Our goal is to divide 99839787 by 290.

Going ahead to step 1:
The number 290 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 290

Let's proceed to step 2:
290 can be fit into 99 0 times, resulting in a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Include the next digit (8) from the dividend after 99, then repeat: 998 / 290

Advancing to step 3:
The number 290 fits into 998 3 times, leaving a remainder of 128.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 870 from 998 and we're left with 128.
Include the next digit (3) from the dividend after 128, then repeat: 1283 / 290

Moving on to step 4:
When dividing 1283 by 290, we get 4 with a remainder of 123.
The next digit of our result is 4. 
Result so far: 34.0
If we subtract 1160 from 1283, we get 123.
Take the next digit (9) from the dividend and append it to 123, then repeat: 1239 / 290

Let's proceed to step 5:
If we divide 1239 by 290, we get 4 and a remainder of 79.
Use 4 as the next digit of our solution. 
Result so far: 344.0
Subtract 1160 from 1239 to get 79.
Include the next digit (7) from the dividend after 79, then repeat: 797 / 290

On to step 6:
When dividing 797 by 290, we get 2 with a remainder of 217.
Write down 2 as next digit of the result. 
Result so far: 3442.0
If we take 580 away from 797, we end up with 217.
Include the next digit (8) from the dividend after 217, then repeat: 2178 / 290

Going ahead to step 7:
290 goes into 2178 7 times with a remainder of 148.
The next digit of our result is 7. 
Result so far: 34427.0
Subtracting 2030 from 2178 leaves us with 148.
Take the next digit (7) from the dividend and append it to 148, then repeat: 1487 / 290

Moving on to step 8:
1487 divided by 290 is 5 with a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 344275.0
Subtract 1450 from 1487 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 9:
370 divided by 290 is 1 with a remainder of 80.
The number 1 becomes the next digit in our result. 
Result so far: 344275.1
If we take 290 away from 370, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
290 can be fit into 800 2 times, resulting in a remainder of 220.
Record the quotient 2 as the next digit in the result. 
Result so far: 344275.12
If we take 580 away from 800, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 11:
If we divide 2200 by 290, we get 7 and a remainder of 170.
Use 7 as the next digit of our solution. 
Result so far: 344275.127
Subtracting 2030 from 2200 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 12:
If we divide 1700 by 290, we get 5 and a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 344275.1275
The remainder is 250 after subtracting 1450 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 13:
2500 divided by 290 is 8 with a remainder of 180.
The number 8 becomes the next digit in our result. 
Result so far: 344275.12758
Deduct 2320 from 2500 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 14:
1800 divided by 290 is 6 with a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 344275.127586
The remainder is 60 after subtracting 1740 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 15:
When dividing 600 by 290, we get 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 344275.1275862
The remainder is 20 after subtracting 580 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 16:
The number 290 fits into 200 0 times, leaving a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 344275.1275862
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 344275.1275862, with a leftover of 2e-07.
