Let's divide 42740254 by 492
We want to figure out the number of times 42740254 can be divided by 492.

Going ahead to step 1:
If we divide 4 by 492, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 492

Step 2:
492 goes into 42 0 times with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Fetch the next digit (7) from the dividend, attach it to 42 and continue: 427 / 492

Advancing to step 3:
427 divided by 492 is 0 with a remainder of 427.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 427 leaves us with 427.
Take the next digit (4) from the dividend and append it to 427, then repeat: 4274 / 492

Let's proceed to step 4:
4274 divided by 492 is 8 with a remainder of 338.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 338 after subtracting 3936 from 4274.
Append the next digit (0) from the dividend to 338 and continue with: 3380 / 492

On to step 5:
When dividing 3380 by 492, we get 6 with a remainder of 428.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Subtracting 2952 from 3380 leaves us with 428.
Append the next digit (2) from the dividend to 428 and continue with: 4282 / 492

Going ahead to step 6:
When dividing 4282 by 492, we get 8 with a remainder of 346.
The number 8 becomes the next digit in our result. 
Result so far: 868.0
Deduct 3936 from 4282 and we're left with 346.
Bring next digit (5) of the dividend behind the 346 and repeat the process: 3465 / 492

On to step 7:
If we divide 3465 by 492, we get 7 and a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 8687.0
Deduct 3444 from 3465 and we're left with 21.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 492

Advancing to step 8:
492 can be fit into 214 0 times, resulting in a remainder of 214.
Put 0 as the next digit of the answer. 
Result so far: 86870.0
The remainder is 214 after subtracting 0 from 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 9:
492 can be fit into 2140 4 times, resulting in a remainder of 172.
Use 4 as the next digit of our solution. 
Result so far: 86870.4
The remainder is 172 after subtracting 1968 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 10:
492 can be fit into 1720 3 times, resulting in a remainder of 244.
Write down 3 as next digit of the result. 
Result so far: 86870.43
Subtract 1476 from 1720 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 11:
The number 492 fits into 2440 4 times, leaving a remainder of 472.
Use 4 as the next digit of our solution. 
Result so far: 86870.434
Subtract 1968 from 2440 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 12:
492 goes into 4720 9 times with a remainder of 292.
The number 9 becomes the next digit in our result. 
Result so far: 86870.4349
Subtract 4428 from 4720 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 13:
2920 divided by 492 is 5 with a remainder of 460.
The number 5 becomes the next digit in our result. 
Result so far: 86870.43495
Subtract 2460 from 2920 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 14:
When dividing 4600 by 492, we get 9 with a remainder of 172.
Record the quotient 9 as the next digit in the result. 
Result so far: 86870.434959
Subtract 4428 from 4600 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 15:
492 goes into 1720 3 times with a remainder of 244.
The number 3 becomes the next digit in our result. 
Result so far: 86870.4349593
If we subtract 1476 from 1720, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 16:
If we divide 2440 by 492, we get 4 and a remainder of 472.
Write down 4 as next digit of the result. 
Result so far: 86870.43495934
Subtract 1968 from 2440 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

The final outcome is 86870.43495934, with a leftover of 4.72e-07.
