91018139 ÷ 468 
We want to figure out the number of times 91018139 can be divided by 468.

Step 1:
468 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 468

Step 2:
468 goes into 91 0 times with a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Include the next digit (0) from the dividend after 91, then repeat: 910 / 468

Let's proceed to step 3:
468 can be fit into 910 1 times, resulting in a remainder of 442.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 468 from 910, we get 442.
Grab the next digit (1) from the dividend, add it to 442, then carry on: 4421 / 468

Let's proceed to step 4:
468 can be fit into 4421 9 times, resulting in a remainder of 209.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 4212 from 4421 leaves us with 209.
Grab the next digit (8) from the dividend, add it to 209, then carry on: 2098 / 468

Moving on to step 5:
The number 468 fits into 2098 4 times, leaving a remainder of 226.
The number 4 becomes the next digit in our result. 
Result so far: 194.0
Subtract 1872 from 2098 to get 226.
Bring next digit (1) of the dividend behind the 226 and repeat the process: 2261 / 468

On to step 6:
If we divide 2261 by 468, we get 4 and a remainder of 389.
The next digit of our result is 4. 
Result so far: 1944.0
Subtracting 1872 from 2261 leaves us with 389.
Grab the next digit (3) from the dividend, add it to 389, then carry on: 3893 / 468

Going ahead to step 7:
When dividing 3893 by 468, we get 8 with a remainder of 149.
Write down 8 as next digit of the result. 
Result so far: 19448.0
Deduct 3744 from 3893 and we're left with 149.
Grab the next digit (9) from the dividend, add it to 149, then carry on: 1499 / 468

On to step 8:
1499 divided by 468 is 3 with a remainder of 95.
The next digit of our result is 3. 
Result so far: 194483.0
Subtract 1404 from 1499 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 9:
When dividing 950 by 468, we get 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 194483.2
Subtract 936 from 950 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
If we divide 140 by 468, we get 0 and a remainder of 140.
The next digit of our result is 0. 
Result so far: 194483.2
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
When dividing 1400 by 468, we get 2 with a remainder of 464.
Record the quotient 2 as the next digit in the result. 
Result so far: 194483.202
Subtract 936 from 1400 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 12:
When dividing 4640 by 468, we get 9 with a remainder of 428.
Write down 9 as next digit of the result. 
Result so far: 194483.2029
If we take 4212 away from 4640, we end up 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.

On to step 13:
468 can be fit into 4280 9 times, resulting in a remainder of 68.
Put 9 as the next digit of the answer. 
Result so far: 194483.20299
If we take 4212 away from 4280, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

In conclusion, the division gives 194483.20299 with a balance of 6.8e-05.
