We look at the division of 634370 by 40 
Our goal is to divide 634370 by 40.

Moving on to step 1:
40 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 40

On to step 2:
40 goes into 63 1 times with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 40 from 63 to get 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 40

Let's proceed to step 3:
When dividing 234 by 40, we get 5 with a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 200 from 234 and we're left with 34.
Append the next digit (3) from the dividend to 34 and continue with: 343 / 40

Going ahead to step 4:
When dividing 343 by 40, we get 8 with a remainder of 23.
Put 8 as the next digit of the answer. 
Result so far: 158.0
If we subtract 320 from 343, we get 23.
Take the next digit (7) from the dividend and append it to 23, then repeat: 237 / 40

Advancing to step 5:
237 divided by 40 is 5 with a remainder of 37.
Use 5 as the next digit of our solution. 
Result so far: 1585.0
If we subtract 200 from 237, we get 37.
Fetch the next digit (0) from the dividend, attach it to 37 and continue: 370 / 40

Advancing to step 6:
If we divide 370 by 40, we get 9 and a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 15859.0
If we subtract 360 from 370, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
If we divide 100 by 40, we get 2 and a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 15859.2
Deduct 80 from 100 and we're left 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.

On to step 8:
40 can be fit into 200 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 15859.25
If we subtract 200 from 200, we get 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 9:
40 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15859.25
Subtracting 0 from 0 leaves us 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.
Put 0 as the next digit of the answer. 
Result so far: 15859.25
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.

In conclusion, the division gives 15859.25 with a balance of 0.0.
