Let's divide 42891373 by 492
We want to figure out the number of times 42891373 can be divided by 492.

Moving on to step 1:
When dividing 4 by 492, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
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

Moving on to step 2:
42 divided by 492 is 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (8) from the dividend and append it to 42, then repeat: 428 / 492

On to step 3:
492 goes into 428 0 times with a remainder of 428.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 428 leaves us with 428.
Bring next digit (9) of the dividend behind the 428 and repeat the process: 4289 / 492

Step 4:
4289 divided by 492 is 8 with a remainder of 353.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 3936 from 4289 and we're left with 353.
Take the next digit (1) from the dividend and append it to 353, then repeat: 3531 / 492

Step 5:
492 goes into 3531 7 times with a remainder of 87.
Put 7 as the next digit of the answer. 
Result so far: 87.0
The remainder is 87 after subtracting 3444 from 3531.
Bring next digit (3) of the dividend behind the 87 and repeat the process: 873 / 492

Let's proceed to step 6:
When dividing 873 by 492, we get 1 with a remainder of 381.
The next digit of our result is 1. 
Result so far: 871.0
Subtracting 492 from 873 leaves us with 381.
Append the next digit (7) from the dividend to 381 and continue with: 3817 / 492

Let's proceed to step 7:
492 can be fit into 3817 7 times, resulting in a remainder of 373.
Put 7 as the next digit of the answer. 
Result so far: 8717.0
If we take 3444 away from 3817, we end up with 373.
Fetch the next digit (3) from the dividend, attach it to 373 and continue: 3733 / 492

Going ahead to step 8:
3733 divided by 492 is 7 with a remainder of 289.
The next digit of our result is 7. 
Result so far: 87177.0
Subtract 3444 from 3733 to get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Going ahead to step 9:
If we divide 2890 by 492, we get 5 and a remainder of 430.
Use 5 as the next digit of our solution. 
Result so far: 87177.5
If we take 2460 away from 2890, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 10:
The number 492 fits into 4300 8 times, leaving a remainder of 364.
The number 8 becomes the next digit in our result. 
Result so far: 87177.58
Subtract 3936 from 4300 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 11:
If we divide 3640 by 492, we get 7 and a remainder of 196.
The next digit of our result is 7. 
Result so far: 87177.587
If we subtract 3444 from 3640, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 12:
If we divide 1960 by 492, we get 3 and a remainder of 484.
Put 3 as the next digit of the answer. 
Result so far: 87177.5873
Subtracting 1476 from 1960 leaves us with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Step 13:
If we divide 4840 by 492, we get 9 and a remainder of 412.
Write down 9 as next digit of the result. 
Result so far: 87177.58739
If we take 4428 away from 4840, we end up with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Step 14:
4120 divided by 492 is 8 with a remainder of 184.
Use 8 as the next digit of our solution. 
Result so far: 87177.587398
Subtracting 3936 from 4120 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 15:
492 can be fit into 1840 3 times, resulting in a remainder of 364.
The number 3 becomes the next digit in our result. 
Result so far: 87177.5873983
Subtract 1476 from 1840 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 16:
492 goes into 3640 7 times with a remainder of 196.
Use 7 as the next digit of our solution. 
Result so far: 87177.58739837
Subtracting 3444 from 3640 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

The final outcome is 87177.58739837, with a leftover of 1.96e-07.
