57869 ÷ 40 
We're looking to find how many times 40 goes into 57869.

Step 1:
40 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 40

Going ahead to step 2:
The number 40 fits into 57 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 40 from 57 to get 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 40

On to step 3:
When dividing 178 by 40, we get 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 160 from 178 and we're left with 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 40

Going ahead to step 4:
The number 40 fits into 186 4 times, leaving a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 144.0
The remainder is 26 after subtracting 160 from 186.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 40

Step 5:
The number 40 fits into 269 6 times, leaving a remainder of 29.
The next digit of our result is 6. 
Result so far: 1446.0
The remainder is 29 after subtracting 240 from 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 6:
290 divided by 40 is 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 1446.7
If we take 280 away from 290, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
40 can be fit into 100 2 times, resulting in a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 1446.72
If we take 80 away from 100, we end up 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.

Step 8:
If we divide 200 by 40, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1446.725
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.

Moving on to 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: 1446.725
If we subtract 0 from 0, 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.

Let's proceed to step 10:
40 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1446.725
Subtract 0 from 0 to 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.

Our division results in 1446.725 with a remaining 0.0.
