We look at the division of 69729720 by 109 
We want to figure out the number of times 69729720 can be divided by 109.

On to step 1:
109 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 109

On to step 2:
69 divided by 109 is 0 with a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 69 after subtracting 0 from 69.
Grab the next digit (7) from the dividend, add it to 69, then carry on: 697 / 109

Advancing to step 3:
109 can be fit into 697 6 times, resulting in a remainder of 43.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 654 away from 697, we end up with 43.
Include the next digit (2) from the dividend after 43, then repeat: 432 / 109

Step 4:
109 goes into 432 3 times with a remainder of 105.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Deduct 327 from 432 and we're left with 105.
Include the next digit (9) from the dividend after 105, then repeat: 1059 / 109

On to step 5:
If we divide 1059 by 109, we get 9 and a remainder of 78.
The number 9 becomes the next digit in our result. 
Result so far: 639.0
Subtract 981 from 1059 to get 78.
Append the next digit (7) from the dividend to 78 and continue with: 787 / 109

Advancing to step 6:
787 divided by 109 is 7 with a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 6397.0
Deduct 763 from 787 and we're left with 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 109

On to step 7:
The number 109 fits into 242 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 63972.0
Subtract 218 from 242 to get 24.
Fetch the next digit (0) from the dividend, attach it to 24 and continue: 240 / 109

Step 8:
If we divide 240 by 109, we get 2 and a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 639722.0
Subtract 218 from 240 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
If we divide 220 by 109, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 639722.2
The remainder is 2 after subtracting 218 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
109 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 639722.2
Deduct 0 from 20 and we're left with 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 11:
The number 109 fits into 200 1 times, leaving a remainder of 91.
Put 1 as the next digit of the answer. 
Result so far: 639722.201
If we subtract 109 from 200, we get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Let's proceed to step 12:
The number 109 fits into 910 8 times, leaving a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 639722.2018
Deduct 872 from 910 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 13:
109 can be fit into 380 3 times, resulting in a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 639722.20183
The remainder is 53 after subtracting 327 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 14:
530 divided by 109 is 4 with a remainder of 94.
Put 4 as the next digit of the answer. 
Result so far: 639722.201834
If we take 436 away from 530, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 15:
If we divide 940 by 109, we get 8 and a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 639722.2018348
Subtract 872 from 940 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 16:
If we divide 680 by 109, we get 6 and a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 639722.20183486
The remainder is 26 after subtracting 654 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

In conclusion, the division gives 639722.20183486 with a balance of 2.6e-08.
