621108 ÷ 43 
Our goal is to divide 621108 by 43.

Going ahead to step 1:
6 divided by 43 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 43

Advancing to step 2:
If we divide 62 by 43, we get 1 and a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 43 from 62, we get 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 43

Moving on to step 3:
191 divided by 43 is 4 with a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 172 from 191 leaves us with 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 43

On to step 4:
When dividing 191 by 43, we get 4 with a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 144.0
The remainder is 19 after subtracting 172 from 191.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 43

Going ahead to step 5:
190 divided by 43 is 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 1444.0
Deduct 172 from 190 and we're left with 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 43

Advancing to step 6:
The number 43 fits into 188 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 14444.0
Deduct 172 from 188 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
When dividing 160 by 43, we get 3 with a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 14444.3
Subtracting 129 from 160 leaves us 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.

Going ahead to step 8:
310 divided by 43 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 14444.37
The remainder is 9 after subtracting 301 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
If we divide 90 by 43, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 14444.372
If we take 86 away from 90, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
When dividing 40 by 43, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 14444.372
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
If we divide 400 by 43, we get 9 and a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 14444.37209
Deduct 387 from 400 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 12:
130 divided by 43 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 14444.372093
The remainder is 1 after subtracting 129 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 13:
The number 43 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 14444.372093
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
The number 43 fits into 100 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 14444.37209302
Deduct 86 from 100 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 14444.37209302 with a remaining 1.4e-08.
