We're dividing 68102457 by 457 
We want to divide 68102457 by 457.

Moving on to step 1:
The number 457 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 457

On to step 2:
457 goes into 68 0 times with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Append the next digit (1) from the dividend to 68 and continue with: 681 / 457

Advancing to step 3:
457 goes into 681 1 times with a remainder of 224.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 457 from 681, we get 224.
Take the next digit (0) from the dividend and append it to 224, then repeat: 2240 / 457

Advancing to step 4:
When dividing 2240 by 457, we get 4 with a remainder of 412.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 1828 from 2240 leaves us with 412.
Fetch the next digit (2) from the dividend, attach it to 412 and continue: 4122 / 457

Going ahead to step 5:
If we divide 4122 by 457, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 149.0
Deduct 4113 from 4122 and we're left with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 457

Let's proceed to step 6:
If we divide 94 by 457, we get 0 and a remainder of 94.
The next digit of our result is 0. 
Result so far: 1490.0
Deduct 0 from 94 and we're left with 94.
Bring next digit (5) of the dividend behind the 94 and repeat the process: 945 / 457

Moving on to step 7:
457 can be fit into 945 2 times, resulting in a remainder of 31.
Use 2 as the next digit of our solution. 
Result so far: 14902.0
The remainder is 31 after subtracting 914 from 945.
Bring next digit (7) of the dividend behind the 31 and repeat the process: 317 / 457

Going ahead to step 8:
457 can be fit into 317 0 times, resulting in a remainder of 317.
Put 0 as the next digit of the answer. 
Result so far: 149020.0
If we take 0 away from 317, we end up with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Moving on to step 9:
3170 divided by 457 is 6 with a remainder of 428.
Record the quotient 6 as the next digit in the result. 
Result so far: 149020.6
Deduct 2742 from 3170 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Going ahead to step 10:
If we divide 4280 by 457, we get 9 and a remainder of 167.
Put 9 as the next digit of the answer. 
Result so far: 149020.69
If we subtract 4113 from 4280, we get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Moving on to step 11:
When dividing 1670 by 457, we get 3 with a remainder of 299.
Use 3 as the next digit of our solution. 
Result so far: 149020.693
Subtract 1371 from 1670 to get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Moving on to step 12:
When dividing 2990 by 457, we get 6 with a remainder of 248.
Record the quotient 6 as the next digit in the result. 
Result so far: 149020.6936
Subtract 2742 from 2990 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 13:
457 goes into 2480 5 times with a remainder of 195.
The next digit of our result is 5. 
Result so far: 149020.69365
Deduct 2285 from 2480 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 14:
The number 457 fits into 1950 4 times, leaving a remainder of 122.
Write down 4 as next digit of the result. 
Result so far: 149020.693654
If we take 1828 away from 1950, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 15:
If we divide 1220 by 457, we get 2 and a remainder of 306.
Put 2 as the next digit of the answer. 
Result so far: 149020.6936542
Deduct 914 from 1220 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Moving on to step 16:
457 goes into 3060 6 times with a remainder of 318.
Write down 6 as next digit of the result. 
Result so far: 149020.69365426
If we take 2742 away from 3060, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

The final result is 149020.69365426 with a remainder of 3.18e-07.
