We divide 121539 by 35
We want to divide 121539 by 35.

Going ahead to step 1:
1 divided by 35 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 35

Moving on to step 2:
35 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 35

Step 3:
35 can be fit into 121 3 times, resulting in a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 105 from 121 leaves us with 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 35

Let's proceed to step 4:
35 can be fit into 165 4 times, resulting in a remainder of 25.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Subtracting 140 from 165 leaves us with 25.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 35

Moving on to step 5:
The number 35 fits into 253 7 times, leaving a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 347.0
Deduct 245 from 253 and we're left with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 35

Going ahead to step 6:
89 divided by 35 is 2 with a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 3472.0
If we subtract 70 from 89, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
35 can be fit into 190 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 3472.5
Subtracting 175 from 190 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
When dividing 150 by 35, we get 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 3472.54
Deduct 140 from 150 and we're left 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.

Let's proceed to step 9:
When dividing 100 by 35, we get 2 with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 3472.542
Deduct 70 from 100 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
When dividing 300 by 35, we get 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 3472.5428
Subtract 280 from 300 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
If we divide 200 by 35, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 3472.54285
The remainder is 25 after subtracting 175 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 12:
35 goes into 250 7 times with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 3472.542857
Deduct 245 from 250 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 13:
When dividing 50 by 35, we get 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 3472.5428571
Deduct 35 from 50 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 14:
35 can be fit into 150 4 times, resulting in a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 3472.54285714
Subtracting 140 from 150 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.

After the division, we end up with 3472.54285714 and a remainder of 1e-08.
