We're dividing 87424453 by 457 
We want to figure out the number of times 87424453 can be divided by 457.

Let's proceed to step 1:
457 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
If we subtract 0 from 8, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 457

Moving on to step 2:
457 can be fit into 87 0 times, resulting in a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Grab the next digit (4) from the dividend, add it to 87, then carry on: 874 / 457

Moving on to step 3:
457 can be fit into 874 1 times, resulting in a remainder of 417.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 457 from 874 leaves us with 417.
Fetch the next digit (2) from the dividend, attach it to 417 and continue: 4172 / 457

Advancing to step 4:
If we divide 4172 by 457, we get 9 and a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we take 4113 away from 4172, we end up with 59.
Take the next digit (4) from the dividend and append it to 59, then repeat: 594 / 457

Moving on to step 5:
If we divide 594 by 457, we get 1 and a remainder of 137.
Record the quotient 1 as the next digit in the result. 
Result so far: 191.0
Deduct 457 from 594 and we're left with 137.
Fetch the next digit (4) from the dividend, attach it to 137 and continue: 1374 / 457

Advancing to step 6:
If we divide 1374 by 457, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 1913.0
Subtract 1371 from 1374 to get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 457

Moving on to step 7:
The number 457 fits into 35 0 times, leaving a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 19130.0
The remainder is 35 after subtracting 0 from 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 457

Step 8:
457 goes into 353 0 times with a remainder of 353.
The next digit of our result is 0. 
Result so far: 191300.0
Subtracting 0 from 353 leaves us with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Moving on to step 9:
457 goes into 3530 7 times with a remainder of 331.
Use 7 as the next digit of our solution. 
Result so far: 191300.7
Deduct 3199 from 3530 and we're left with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Step 10:
457 goes into 3310 7 times with a remainder of 111.
Use 7 as the next digit of our solution. 
Result so far: 191300.77
Deduct 3199 from 3310 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Our division results in 191300.77 with a remaining 0.111.
