We look at the division of 45192043 by 810 
We want to figure out the number of times 45192043 can be divided by 810.

On to step 1:
The number 810 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 810

Let's proceed to step 2:
The number 810 fits into 45 0 times, leaving a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Fetch the next digit (1) from the dividend, attach it to 45 and continue: 451 / 810

Advancing to step 3:
810 can be fit into 451 0 times, resulting in a remainder of 451.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 451 and we're left with 451.
Bring next digit (9) of the dividend behind the 451 and repeat the process: 4519 / 810

Going ahead to step 4:
810 goes into 4519 5 times with a remainder of 469.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 4050 from 4519 to get 469.
Append the next digit (2) from the dividend to 469 and continue with: 4692 / 810

Advancing to step 5:
If we divide 4692 by 810, we get 5 and a remainder of 642.
The next digit of our result is 5. 
Result so far: 55.0
Subtract 4050 from 4692 to get 642.
Grab the next digit (0) from the dividend, add it to 642, then carry on: 6420 / 810

Step 6:
810 goes into 6420 7 times with a remainder of 750.
Put 7 as the next digit of the answer. 
Result so far: 557.0
Deduct 5670 from 6420 and we're left with 750.
Take the next digit (4) from the dividend and append it to 750, then repeat: 7504 / 810

Going ahead to step 7:
810 goes into 7504 9 times with a remainder of 214.
Put 9 as the next digit of the answer. 
Result so far: 5579.0
If we subtract 7290 from 7504, we get 214.
Include the next digit (3) from the dividend after 214, then repeat: 2143 / 810

Step 8:
The number 810 fits into 2143 2 times, leaving a remainder of 523.
Record the quotient 2 as the next digit in the result. 
Result so far: 55792.0
If we subtract 1620 from 2143, we get 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Moving on to step 9:
The number 810 fits into 5230 6 times, leaving a remainder of 370.
Record the quotient 6 as the next digit in the result. 
Result so far: 55792.6
Deduct 4860 from 5230 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 10:
The number 810 fits into 3700 4 times, leaving a remainder of 460.
Record the quotient 4 as the next digit in the result. 
Result so far: 55792.64
Subtracting 3240 from 3700 leaves us with 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 11:
4600 divided by 810 is 5 with a remainder of 550.
Use 5 as the next digit of our solution. 
Result so far: 55792.645
If we subtract 4050 from 4600, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Advancing to step 12:
810 goes into 5500 6 times with a remainder of 640.
The number 6 becomes the next digit in our result. 
Result so far: 55792.6456
If we take 4860 away from 5500, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 13:
810 can be fit into 6400 7 times, resulting in a remainder of 730.
Use 7 as the next digit of our solution. 
Result so far: 55792.64567
If we take 5670 away from 6400, we end up with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Step 14:
If we divide 7300 by 810, we get 9 and a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 55792.645679
The remainder is 10 after subtracting 7290 from 7300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 15:
The number 810 fits into 100 0 times, leaving a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 55792.645679
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 16:
1000 divided by 810 is 1 with a remainder of 190.
The next digit of our result is 1. 
Result so far: 55792.64567901
If we take 810 away from 1000, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Our division results in 55792.64567901 with a remaining 1.9e-07.
