135421 ÷ 35 
We want to divide 135421 by 35.

Moving on to step 1:
35 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 35

On to step 2:
35 goes into 13 0 times with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 35

Going ahead to step 3:
35 can be fit into 135 3 times, resulting in a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 105 from 135, we get 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 35

Going ahead to step 4:
304 divided by 35 is 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtracting 280 from 304 leaves us with 24.
Fetch the next digit (2) from the dividend, attach it to 24 and continue: 242 / 35

Advancing to step 5:
If we divide 242 by 35, we get 6 and a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 386.0
Subtracting 210 from 242 leaves us with 32.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 35

Step 6:
35 can be fit into 321 9 times, resulting in a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 3869.0
The remainder is 6 after subtracting 315 from 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
If we divide 60 by 35, we get 1 and a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 3869.1
Subtracting 35 from 60 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.

Going ahead 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: 3869.17
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 can be fit into 50 1 times, resulting in a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 3869.171
If we subtract 35 from 50, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
150 divided by 35 is 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 3869.1714
The remainder is 10 after subtracting 140 from 150.
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 11:
The number 35 fits into 100 2 times, leaving a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 3869.17142
The remainder is 30 after subtracting 70 from 100.
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 12:
300 divided by 35 is 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 3869.171428
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.

On to step 13:
35 goes into 200 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 3869.1714285
Subtract 175 from 200 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 14:
If we divide 250 by 35, we get 7 and a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 3869.17142857
The remainder is 5 after subtracting 245 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 3869.17142857 with a remainder of 5e-09.
