73840 ÷ 69 
We want to figure out the number of times 73840 can be divided by 69.

On to step 1:
The number 69 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 69

On to step 2:
69 can be fit into 73 1 times, resulting in a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 69 from 73, we get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 69

Let's proceed to step 3:
When dividing 48 by 69, we get 0 with a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 48 and we're left with 48.
Bring next digit (4) of the dividend behind the 48 and repeat the process: 484 / 69

Going ahead to step 4:
69 goes into 484 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
Deduct 483 from 484 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 69

Advancing to step 5:
10 divided by 69 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1070.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 6:
If we divide 100 by 69, we get 1 and a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1070.1
Subtracting 69 from 100 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.

On to step 7:
When dividing 310 by 69, we get 4 with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 1070.14
Subtract 276 from 310 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
69 can be fit into 340 4 times, resulting in a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 1070.144
Deduct 276 from 340 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 1070.144 with a remainder of 0.0064.
