40154874 ÷ 285 
Let's see how many times 285 fits into 40154874.

Step 1:
When dividing 4 by 285, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 285

On to step 2:
The number 285 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 285

On to step 3:
If we divide 401 by 285, we get 1 and a remainder of 116.
The next digit of our result is 1. 
Result so far: 1.0
If we take 285 away from 401, we end up with 116.
Include the next digit (5) from the dividend after 116, then repeat: 1165 / 285

On to step 4:
285 goes into 1165 4 times with a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we take 1140 away from 1165, we end up with 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 285

Going ahead to step 5:
If we divide 254 by 285, we get 0 and a remainder of 254.
Write down 0 as next digit of the result. 
Result so far: 140.0
The remainder is 254 after subtracting 0 from 254.
Take the next digit (8) from the dividend and append it to 254, then repeat: 2548 / 285

Advancing to step 6:
285 goes into 2548 8 times with a remainder of 268.
Write down 8 as next digit of the result. 
Result so far: 1408.0
If we subtract 2280 from 2548, we get 268.
Bring next digit (7) of the dividend behind the 268 and repeat the process: 2687 / 285

Step 7:
If we divide 2687 by 285, we get 9 and a remainder of 122.
The next digit of our result is 9. 
Result so far: 14089.0
Subtract 2565 from 2687 to get 122.
Include the next digit (4) from the dividend after 122, then repeat: 1224 / 285

Let's proceed to step 8:
285 goes into 1224 4 times with a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 140894.0
The remainder is 84 after subtracting 1140 from 1224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 9:
When dividing 840 by 285, we get 2 with a remainder of 270.
Record the quotient 2 as the next digit in the result. 
Result so far: 140894.2
The remainder is 270 after subtracting 570 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 10:
285 goes into 2700 9 times with a remainder of 135.
Use 9 as the next digit of our solution. 
Result so far: 140894.29
Deduct 2565 from 2700 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 11:
1350 divided by 285 is 4 with a remainder of 210.
Record the quotient 4 as the next digit in the result. 
Result so far: 140894.294
The remainder is 210 after subtracting 1140 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 12:
2100 divided by 285 is 7 with a remainder of 105.
Use 7 as the next digit of our solution. 
Result so far: 140894.2947
If we take 1995 away from 2100, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 13:
If we divide 1050 by 285, we get 3 and a remainder of 195.
The next digit of our result is 3. 
Result so far: 140894.29473
Subtract 855 from 1050 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 14:
1950 divided by 285 is 6 with a remainder of 240.
Write down 6 as next digit of the result. 
Result so far: 140894.294736
The remainder is 240 after subtracting 1710 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 15:
The number 285 fits into 2400 8 times, leaving a remainder of 120.
Record the quotient 8 as the next digit in the result. 
Result so far: 140894.2947368
The remainder is 120 after subtracting 2280 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 16:
When dividing 1200 by 285, we get 4 with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 140894.29473684
Deduct 1140 from 1200 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 140894.29473684, and the remainder is 6e-08.
