109840 ÷ 79 
We want to figure out the number of times 109840 can be divided by 79.

Let's proceed to step 1:
If we divide 1 by 79, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 79

Step 2:
The number 79 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 79

Step 3:
79 goes into 109 1 times with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 79 from 109 to get 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 79

On to step 4:
308 divided by 79 is 3 with a remainder of 71.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 237 away from 308, we end up with 71.
Take the next digit (4) from the dividend and append it to 71, then repeat: 714 / 79

Advancing to step 5:
If we divide 714 by 79, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 139.0
If we take 711 away from 714, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 79

Step 6:
30 divided by 79 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 1390.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
300 divided by 79 is 3 with a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 1390.3
Subtract 237 from 300 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 8:
The number 79 fits into 630 7 times, leaving a remainder of 77.
Put 7 as the next digit of the answer. 
Result so far: 1390.37
Deduct 553 from 630 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 9:
770 divided by 79 is 9 with a remainder of 59.
Record the quotient 9 as the next digit in the result. 
Result so far: 1390.379
Subtract 711 from 770 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 10:
The number 79 fits into 590 7 times, leaving a remainder of 37.
The next digit of our result is 7. 
Result so far: 1390.3797
Subtracting 553 from 590 leaves us 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:
If we divide 370 by 79, we get 4 and a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 1390.37974
Subtracting 316 from 370 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 12:
The number 79 fits into 540 6 times, leaving a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 1390.379746
If we subtract 474 from 540, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 13:
If we divide 660 by 79, we get 8 and a remainder of 28.
The next digit of our result is 8. 
Result so far: 1390.3797468
Subtracting 632 from 660 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 14:
280 divided by 79 is 3 with a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 1390.37974683
Subtract 237 from 280 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The quotient of the division is 1390.37974683, and the remainder is 4.3e-08.
