Let's divide 434207 by 40
We want to divide 434207 by 40.

Step 1:
If we divide 4 by 40, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 40

Moving on to step 2:
If we divide 43 by 40, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 40 from 43 leaves us with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 40

On to step 3:
34 divided by 40 is 0 with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 34 to get 34.
Grab the next digit (2) from the dividend, add it to 34, then carry on: 342 / 40

Going ahead to step 4:
If we divide 342 by 40, we get 8 and a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 108.0
Deduct 320 from 342 and we're left with 22.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 40

Let's proceed to step 5:
220 divided by 40 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 1085.0
Subtracting 200 from 220 leaves us with 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 40

On to step 6:
40 goes into 207 5 times with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 10855.0
Subtracting 200 from 207 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
When dividing 70 by 40, we get 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 10855.1
If we subtract 40 from 70, we get 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 8:
When dividing 300 by 40, we get 7 with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 10855.17
Subtracting 280 from 300 leaves us 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 9:
40 goes into 200 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 10855.175
If we take 200 away from 200, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10855.175
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
40 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10855.175
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 10855.175 and a remainder of 0.0.
