Let's divide 121820 by 35
Our goal is to divide 121820 by 35.

Going ahead to step 1:
When dividing 1 by 35, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 35

Going ahead to step 2:
35 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 35

On to step 3:
If we divide 121 by 35, we get 3 and a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 105 from 121, we get 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 35

Step 4:
35 goes into 168 4 times with a remainder of 28.
The next digit of our result is 4. 
Result so far: 34.0
Subtracting 140 from 168 leaves us with 28.
Bring next digit (2) of the dividend behind the 28 and repeat the process: 282 / 35

Step 5:
When dividing 282 by 35, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 348.0
Deduct 280 from 282 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 35

Advancing to step 6:
20 divided by 35 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 3480.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
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: 3480.5
Subtracting 175 from 200 leaves us with 25.
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 8:
The number 35 fits into 250 7 times, leaving a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 3480.57
Subtracting 245 from 250 leaves us 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.

Let's proceed to step 9:
35 goes into 50 1 times with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 3480.571
The remainder is 15 after subtracting 35 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
When dividing 150 by 35, we get 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 3480.5714
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.

Let's proceed to step 11:
35 goes into 100 2 times with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 3480.57142
Subtracting 70 from 100 leaves us 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.

Step 12:
The number 35 fits into 300 8 times, leaving a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 3480.571428
If we take 280 away from 300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
When dividing 200 by 35, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 3480.5714285
Deduct 175 from 200 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 14:
35 goes into 250 7 times with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 3480.57142857
If we subtract 245 from 250, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 3480.57142857 and a remainder of 5e-09.
