We're dividing 169170 by 40 
Our goal is to divide 169170 by 40.

Step 1:
40 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 40

Let's proceed to step 2:
The number 40 fits into 16 0 times, leaving a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 40

Advancing to step 3:
40 can be fit into 169 4 times, resulting in a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 9 after subtracting 160 from 169.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 40

Moving on to step 4:
40 goes into 91 2 times with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtracting 80 from 91 leaves us with 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 40

Moving on to step 5:
40 goes into 117 2 times with a remainder of 37.
The next digit of our result is 2. 
Result so far: 422.0
Subtract 80 from 117 to get 37.
Fetch the next digit (0) from the dividend, attach it to 37 and continue: 370 / 40

Moving on to step 6:
When dividing 370 by 40, we get 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 4229.0
Subtract 360 from 370 to 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.

Let's proceed 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: 4229.2
Subtracting 80 from 100 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.

Going ahead to step 8:
200 divided by 40 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 4229.25
Deduct 200 from 200 and we're left 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.

Step 9:
40 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4229.25
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.

Let's proceed to step 10:
When dividing 0 by 40, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4229.25
Deduct 0 from 0 and we're left 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.

The quotient of the division is 4229.25, and the remainder is 0.0.
