71579436 ÷ 109 
Our goal is to divide 71579436 by 109.

Moving on to step 1:
109 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 109

Moving on to step 2:
The number 109 fits into 71 0 times, leaving a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Grab the next digit (5) from the dividend, add it to 71, then carry on: 715 / 109

Moving on to step 3:
If we divide 715 by 109, we get 6 and a remainder of 61.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 654 away from 715, we end up with 61.
Take the next digit (7) from the dividend and append it to 61, then repeat: 617 / 109

On to step 4:
If we divide 617 by 109, we get 5 and a remainder of 72.
Use 5 as the next digit of our solution. 
Result so far: 65.0
If we take 545 away from 617, we end up with 72.
Grab the next digit (9) from the dividend, add it to 72, then carry on: 729 / 109

Moving on to step 5:
109 can be fit into 729 6 times, resulting in a remainder of 75.
Put 6 as the next digit of the answer. 
Result so far: 656.0
Subtracting 654 from 729 leaves us with 75.
Bring next digit (4) of the dividend behind the 75 and repeat the process: 754 / 109

On to step 6:
If we divide 754 by 109, we get 6 and a remainder of 100.
The next digit of our result is 6. 
Result so far: 6566.0
Subtracting 654 from 754 leaves us with 100.
Grab the next digit (3) from the dividend, add it to 100, then carry on: 1003 / 109

Step 7:
When dividing 1003 by 109, we get 9 with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 65669.0
If we take 981 away from 1003, we end up with 22.
Take the next digit (6) from the dividend and append it to 22, then repeat: 226 / 109

Let's proceed to step 8:
226 divided by 109 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 656692.0
If we subtract 218 from 226, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
The number 109 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 656692.0
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
800 divided by 109 is 7 with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 656692.07
Deduct 763 from 800 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 11:
When dividing 370 by 109, we get 3 with a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 656692.073
If we take 327 away from 370, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 12:
109 can be fit into 430 3 times, resulting in a remainder of 103.
The next digit of our result is 3. 
Result so far: 656692.0733
If we subtract 327 from 430, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

After the division, we end up with 656692.0733 and a remainder of 0.00103.
