We look at the division of 10091378 by 543 
We're looking to find how many times 543 goes into 10091378.

Moving on to step 1:
The number 543 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 543

Going ahead to step 2:
543 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 543

Going ahead to step 3:
543 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 100, we end up with 100.
Fetch the next digit (9) from the dividend, attach it to 100 and continue: 1009 / 543

Step 4:
1009 divided by 543 is 1 with a remainder of 466.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 543 away from 1009, we end up with 466.
Include the next digit (1) from the dividend after 466, then repeat: 4661 / 543

Step 5:
543 goes into 4661 8 times with a remainder of 317.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtract 4344 from 4661 to get 317.
Bring next digit (3) of the dividend behind the 317 and repeat the process: 3173 / 543

Step 6:
When dividing 3173 by 543, we get 5 with a remainder of 458.
The number 5 becomes the next digit in our result. 
Result so far: 185.0
Subtracting 2715 from 3173 leaves us with 458.
Append the next digit (7) from the dividend to 458 and continue with: 4587 / 543

Advancing to step 7:
When dividing 4587 by 543, we get 8 with a remainder of 243.
Write down 8 as next digit of the result. 
Result so far: 1858.0
Deduct 4344 from 4587 and we're left with 243.
Grab the next digit (8) from the dividend, add it to 243, then carry on: 2438 / 543

Moving on to step 8:
The number 543 fits into 2438 4 times, leaving a remainder of 266.
Write down 4 as next digit of the result. 
Result so far: 18584.0
If we take 2172 away from 2438, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

On to step 9:
543 can be fit into 2660 4 times, resulting in a remainder of 488.
The number 4 becomes the next digit in our result. 
Result so far: 18584.4
If we take 2172 away from 2660, we end up with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Let's proceed to step 10:
543 can be fit into 4880 8 times, resulting in a remainder of 536.
Record the quotient 8 as the next digit in the result. 
Result so far: 18584.48
If we take 4344 away from 4880, we end up with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Advancing to step 11:
543 can be fit into 5360 9 times, resulting in a remainder of 473.
Use 9 as the next digit of our solution. 
Result so far: 18584.489
If we subtract 4887 from 5360, we get 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

On to step 12:
The number 543 fits into 4730 8 times, leaving a remainder of 386.
The number 8 becomes the next digit in our result. 
Result so far: 18584.4898
Subtract 4344 from 4730 to get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Advancing to step 13:
When dividing 3860 by 543, we get 7 with a remainder of 59.
Record the quotient 7 as the next digit in the result. 
Result so far: 18584.48987
If we take 3801 away from 3860, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 14:
If we divide 590 by 543, we get 1 and a remainder of 47.
The next digit of our result is 1. 
Result so far: 18584.489871
The remainder is 47 after subtracting 543 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 15:
If we divide 470 by 543, we get 0 and a remainder of 470.
Record the quotient 0 as the next digit in the result. 
Result so far: 18584.489871
If we subtract 0 from 470, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

On to step 16:
If we divide 4700 by 543, we get 8 and a remainder of 356.
Use 8 as the next digit of our solution. 
Result so far: 18584.48987108
If we take 4344 away from 4700, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

The final outcome is 18584.48987108, with a leftover of 3.56e-07.
