We look at the division of 450019 by 57 
Our goal is to divide 450019 by 57.

Going ahead to step 1:
57 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 57

Advancing to step 2:
57 can be fit into 45 0 times, resulting in a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Bring next digit (0) of the dividend behind the 45 and repeat the process: 450 / 57

Going ahead to step 3:
The number 57 fits into 450 7 times, leaving a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 399 from 450, we get 51.
Grab the next digit (0) from the dividend, add it to 51, then carry on: 510 / 57

Moving on to step 4:
57 can be fit into 510 8 times, resulting in a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 78.0
If we subtract 456 from 510, we get 54.
Include the next digit (1) from the dividend after 54, then repeat: 541 / 57

On to step 5:
If we divide 541 by 57, we get 9 and a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 789.0
The remainder is 28 after subtracting 513 from 541.
Append the next digit (9) from the dividend to 28 and continue with: 289 / 57

On to step 6:
57 can be fit into 289 5 times, resulting in a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 7895.0
If we subtract 285 from 289, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
57 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 7895.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
57 goes into 400 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 7895.07
The remainder is 1 after subtracting 399 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
57 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 7895.07
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
The number 57 fits into 100 1 times, leaving a remainder of 43.
The next digit of our result is 1. 
Result so far: 7895.0701
If we subtract 57 from 100, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 11:
57 goes into 430 7 times with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 7895.07017
If we subtract 399 from 430, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 12:
310 divided by 57 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 7895.070175
Subtracting 285 from 310 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
If we divide 250 by 57, we get 4 and a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 7895.0701754
The remainder is 22 after subtracting 228 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
57 goes into 220 3 times with a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 7895.07017543
Deduct 171 from 220 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

After the division, we end up with 7895.07017543 and a remainder of 4.9e-08.
