We look at the division of 81150837 by 423 
We're looking to find how many times 423 goes into 81150837.

Moving on to step 1:
423 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 423

Advancing to step 2:
81 divided by 423 is 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Fetch the next digit (1) from the dividend, attach it to 81 and continue: 811 / 423

On to step 3:
If we divide 811 by 423, we get 1 and a remainder of 388.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 423 from 811 leaves us with 388.
Bring next digit (5) of the dividend behind the 388 and repeat the process: 3885 / 423

Advancing to step 4:
423 can be fit into 3885 9 times, resulting in a remainder of 78.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 78 after subtracting 3807 from 3885.
Fetch the next digit (0) from the dividend, attach it to 78 and continue: 780 / 423

Going ahead to step 5:
When dividing 780 by 423, we get 1 with a remainder of 357.
The next digit of our result is 1. 
Result so far: 191.0
If we subtract 423 from 780, we get 357.
Append the next digit (8) from the dividend to 357 and continue with: 3578 / 423

Moving on to step 6:
When dividing 3578 by 423, we get 8 with a remainder of 194.
Record the quotient 8 as the next digit in the result. 
Result so far: 1918.0
The remainder is 194 after subtracting 3384 from 3578.
Take the next digit (3) from the dividend and append it to 194, then repeat: 1943 / 423

Moving on to step 7:
423 goes into 1943 4 times with a remainder of 251.
Use 4 as the next digit of our solution. 
Result so far: 19184.0
Subtracting 1692 from 1943 leaves us with 251.
Fetch the next digit (7) from the dividend, attach it to 251 and continue: 2517 / 423

Moving on to step 8:
The number 423 fits into 2517 5 times, leaving a remainder of 402.
Record the quotient 5 as the next digit in the result. 
Result so far: 191845.0
Subtracting 2115 from 2517 leaves us with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Let's proceed to step 9:
4020 divided by 423 is 9 with a remainder of 213.
The number 9 becomes the next digit in our result. 
Result so far: 191845.9
The remainder is 213 after subtracting 3807 from 4020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Moving on to step 10:
423 goes into 2130 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 191845.95
Subtracting 2115 from 2130 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 11:
When dividing 150 by 423, we get 0 with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 191845.95
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 12:
If we divide 1500 by 423, we get 3 and a remainder of 231.
The number 3 becomes the next digit in our result. 
Result so far: 191845.9503
The remainder is 231 after subtracting 1269 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Advancing to step 13:
When dividing 2310 by 423, we get 5 with a remainder of 195.
Put 5 as the next digit of the answer. 
Result so far: 191845.95035
The remainder is 195 after subtracting 2115 from 2310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 14:
If we divide 1950 by 423, we get 4 and a remainder of 258.
Record the quotient 4 as the next digit in the result. 
Result so far: 191845.950354
Deduct 1692 from 1950 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Moving on to step 15:
423 goes into 2580 6 times with a remainder of 42.
The next digit of our result is 6. 
Result so far: 191845.9503546
If we take 2538 away from 2580, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 16:
When dividing 420 by 423, we get 0 with a remainder of 420.
The next digit of our result is 0. 
Result so far: 191845.9503546
If we subtract 0 from 420, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

After the division, we end up with 191845.9503546 and a remainder of 4.2e-07.
