Let's divide 99489419 by 457
We're looking to find how many times 457 goes into 99489419.

Going ahead to step 1:
457 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 457

Moving on to step 2:
When dividing 99 by 457, we get 0 with a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Fetch the next digit (4) from the dividend, attach it to 99 and continue: 994 / 457

Let's proceed to step 3:
The number 457 fits into 994 2 times, leaving a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 914 from 994, we get 80.
Take the next digit (8) from the dividend and append it to 80, then repeat: 808 / 457

On to step 4:
If we divide 808 by 457, we get 1 and a remainder of 351.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtracting 457 from 808 leaves us with 351.
Bring next digit (9) of the dividend behind the 351 and repeat the process: 3519 / 457

Advancing to step 5:
When dividing 3519 by 457, we get 7 with a remainder of 320.
Put 7 as the next digit of the answer. 
Result so far: 217.0
If we subtract 3199 from 3519, we get 320.
Append the next digit (4) from the dividend to 320 and continue with: 3204 / 457

Step 6:
3204 divided by 457 is 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 2177.0
Subtract 3199 from 3204 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 457

Step 7:
457 can be fit into 51 0 times, resulting in a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 21770.0
If we subtract 0 from 51, we get 51.
Take the next digit (9) from the dividend and append it to 51, then repeat: 519 / 457

Going ahead to step 8:
457 can be fit into 519 1 times, resulting in a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 217701.0
Deduct 457 from 519 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 9:
The number 457 fits into 620 1 times, leaving a remainder of 163.
Write down 1 as next digit of the result. 
Result so far: 217701.1
If we subtract 457 from 620, we get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

On to step 10:
When dividing 1630 by 457, we get 3 with a remainder of 259.
Write down 3 as next digit of the result. 
Result so far: 217701.13
The remainder is 259 after subtracting 1371 from 1630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

On to step 11:
457 goes into 2590 5 times with a remainder of 305.
The number 5 becomes the next digit in our result. 
Result so far: 217701.135
Subtract 2285 from 2590 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Let's proceed to step 12:
When dividing 3050 by 457, we get 6 with a remainder of 308.
The number 6 becomes the next digit in our result. 
Result so far: 217701.1356
The remainder is 308 after subtracting 2742 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 13:
The number 457 fits into 3080 6 times, leaving a remainder of 338.
Write down 6 as next digit of the result. 
Result so far: 217701.13566
Deduct 2742 from 3080 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

The final outcome is 217701.13566, with a leftover of 0.000338.
