421801 ÷ 35 
Our goal is to divide 421801 by 35.

Moving on to step 1:
If we divide 4 by 35, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 35

Going ahead to step 2:
35 can be fit into 42 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 35 from 42 leaves us with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 35

Advancing to step 3:
The number 35 fits into 71 2 times, leaving a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 70 from 71, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 35

Step 4:
The number 35 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 120.0
If we subtract 0 from 18, we get 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 35

Going ahead to step 5:
If we divide 180 by 35, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 1205.0
Subtract 175 from 180 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 35

Advancing to step 6:
51 divided by 35 is 1 with a remainder of 16.
The next digit of our result is 1. 
Result so far: 12051.0
If we subtract 35 from 51, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
The number 35 fits into 160 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 12051.4
If we subtract 140 from 160, we 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.

Going ahead to step 8:
35 can be fit into 200 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 12051.45
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.

Advancing to step 9:
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: 12051.457
If we take 245 away from 250, we end up 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.

On to step 10:
When dividing 50 by 35, we get 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 12051.4571
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.

Going ahead to step 11:
If we divide 150 by 35, we get 4 and a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 12051.45714
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.

Let's proceed to step 12:
100 divided by 35 is 2 with a remainder of 30.
The next digit of our result is 2. 
Result so far: 12051.457142
If we take 70 away from 100, we end up 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 13:
If we divide 300 by 35, we get 8 and a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 12051.4571428
If we subtract 280 from 300, we 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 14:
The number 35 fits into 200 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 12051.45714285
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.

The quotient of the division is 12051.45714285, and the remainder is 2.5e-08.
