121864 ÷ 98 
Let's see how many times 98 fits into 121864.

Advancing to step 1:
When dividing 1 by 98, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 98

Going ahead to step 2:
If we divide 12 by 98, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 98

Advancing to step 3:
When dividing 121 by 98, we get 1 with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 98 from 121 to get 23.
Include the next digit (8) from the dividend after 23, then repeat: 238 / 98

Advancing to step 4:
The number 98 fits into 238 2 times, leaving a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 196 from 238 to get 42.
Grab the next digit (6) from the dividend, add it to 42, then carry on: 426 / 98

Step 5:
98 can be fit into 426 4 times, resulting in a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 124.0
Subtract 392 from 426 to get 34.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 98

Let's proceed to step 6:
When dividing 344 by 98, we get 3 with a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 1243.0
If we take 294 away from 344, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 7:
When dividing 500 by 98, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 1243.5
Subtracting 490 from 500 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
If we divide 100 by 98, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1243.51
If we subtract 98 from 100, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
98 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1243.51
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
200 divided by 98 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 1243.5102
The remainder is 4 after subtracting 196 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
The number 98 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 1243.5102
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
98 goes into 400 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 1243.510204
If we take 392 away from 400, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
The number 98 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 1243.510204
If we take 0 away from 80, 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.

Advancing to step 14:
800 divided by 98 is 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 1243.51020408
The remainder is 16 after subtracting 784 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 1243.51020408 with a remainder of 1.6e-08.
