We're dividing 78785507 by 457 
We're looking to find how many times 457 goes into 78785507.

Let's proceed to step 1:
When dividing 7 by 457, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 457

On to step 2:
The number 457 fits into 78 0 times, leaving a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Include the next digit (7) from the dividend after 78, then repeat: 787 / 457

On to step 3:
457 can be fit into 787 1 times, resulting in a remainder of 330.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 457 away from 787, we end up with 330.
Include the next digit (8) from the dividend after 330, then repeat: 3308 / 457

Let's proceed to step 4:
The number 457 fits into 3308 7 times, leaving a remainder of 109.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 3199 from 3308 to get 109.
Fetch the next digit (5) from the dividend, attach it to 109 and continue: 1095 / 457

Going ahead to step 5:
When dividing 1095 by 457, we get 2 with a remainder of 181.
Put 2 as the next digit of the answer. 
Result so far: 172.0
If we take 914 away from 1095, we end up with 181.
Take the next digit (5) from the dividend and append it to 181, then repeat: 1815 / 457

Going ahead to step 6:
1815 divided by 457 is 3 with a remainder of 444.
Write down 3 as next digit of the result. 
Result so far: 1723.0
The remainder is 444 after subtracting 1371 from 1815.
Fetch the next digit (0) from the dividend, attach it to 444 and continue: 4440 / 457

Advancing to step 7:
457 goes into 4440 9 times with a remainder of 327.
Use 9 as the next digit of our solution. 
Result so far: 17239.0
The remainder is 327 after subtracting 4113 from 4440.
Bring next digit (7) of the dividend behind the 327 and repeat the process: 3277 / 457

Advancing to step 8:
When dividing 3277 by 457, we get 7 with a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 172397.0
The remainder is 78 after subtracting 3199 from 3277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 9:
When dividing 780 by 457, we get 1 with a remainder of 323.
The number 1 becomes the next digit in our result. 
Result so far: 172397.1
Subtracting 457 from 780 leaves us with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Step 10:
457 can be fit into 3230 7 times, resulting in a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 172397.17
If we take 3199 away from 3230, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 11:
When dividing 310 by 457, we get 0 with a remainder of 310.
Put 0 as the next digit of the answer. 
Result so far: 172397.17
If we take 0 away from 310, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 12:
457 goes into 3100 6 times with a remainder of 358.
The next digit of our result is 6. 
Result so far: 172397.1706
Deduct 2742 from 3100 and we're left with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

On to step 13:
457 goes into 3580 7 times with a remainder of 381.
Write down 7 as next digit of the result. 
Result so far: 172397.17067
If we subtract 3199 from 3580, we get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

On to step 14:
If we divide 3810 by 457, we get 8 and a remainder of 154.
Use 8 as the next digit of our solution. 
Result so far: 172397.170678
If we subtract 3656 from 3810, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 15:
If we divide 1540 by 457, we get 3 and a remainder of 169.
Write down 3 as next digit of the result. 
Result so far: 172397.1706783
Subtract 1371 from 1540 to get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Let's proceed to step 16:
1690 divided by 457 is 3 with a remainder of 319.
The number 3 becomes the next digit in our result. 
Result so far: 172397.17067833
If we subtract 1371 from 1690, we get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

After the division, we end up with 172397.17067833 and a remainder of 3.19e-07.
