68138003 ÷ 468 
Our goal is to divide 68138003 by 468.

Going ahead to step 1:
When dividing 6 by 468, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 468

Let's proceed to step 2:
When dividing 68 by 468, we get 0 with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Include the next digit (1) from the dividend after 68, then repeat: 681 / 468

Moving on to step 3:
When dividing 681 by 468, we get 1 with a remainder of 213.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 468 from 681 leaves us with 213.
Take the next digit (3) from the dividend and append it to 213, then repeat: 2133 / 468

Advancing to step 4:
When dividing 2133 by 468, we get 4 with a remainder of 261.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 1872 from 2133, we get 261.
Fetch the next digit (8) from the dividend, attach it to 261 and continue: 2618 / 468

Step 5:
The number 468 fits into 2618 5 times, leaving a remainder of 278.
Use 5 as the next digit of our solution. 
Result so far: 145.0
Deduct 2340 from 2618 and we're left with 278.
Grab the next digit (0) from the dividend, add it to 278, then carry on: 2780 / 468

On to step 6:
If we divide 2780 by 468, we get 5 and a remainder of 440.
Put 5 as the next digit of the answer. 
Result so far: 1455.0
If we subtract 2340 from 2780, we get 440.
Take the next digit (0) from the dividend and append it to 440, then repeat: 4400 / 468

Let's proceed to step 7:
468 can be fit into 4400 9 times, resulting in a remainder of 188.
The next digit of our result is 9. 
Result so far: 14559.0
If we take 4212 away from 4400, we end up with 188.
Grab the next digit (3) from the dividend, add it to 188, then carry on: 1883 / 468

On to step 8:
1883 divided by 468 is 4 with a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 145594.0
Subtract 1872 from 1883 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
The number 468 fits into 110 0 times, leaving a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 145594.0
If we subtract 0 from 110, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 10:
The number 468 fits into 1100 2 times, leaving a remainder of 164.
Put 2 as the next digit of the answer. 
Result so far: 145594.02
If we take 936 away from 1100, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 11:
When dividing 1640 by 468, we get 3 with a remainder of 236.
Record the quotient 3 as the next digit in the result. 
Result so far: 145594.023
If we subtract 1404 from 1640, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Moving on to step 12:
The number 468 fits into 2360 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 145594.0235
If we subtract 2340 from 2360, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
The number 468 fits into 200 0 times, leaving a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 145594.0235
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 14:
If we divide 2000 by 468, we get 4 and a remainder of 128.
Put 4 as the next digit of the answer. 
Result so far: 145594.023504
If we take 1872 away from 2000, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 15:
468 goes into 1280 2 times with a remainder of 344.
The number 2 becomes the next digit in our result. 
Result so far: 145594.0235042
Subtract 936 from 1280 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

On to step 16:
When dividing 3440 by 468, we get 7 with a remainder of 164.
Record the quotient 7 as the next digit in the result. 
Result so far: 145594.02350427
Deduct 3276 from 3440 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

The final outcome is 145594.02350427, with a leftover of 1.64e-07.
