Let's divide 169940 by 77
We want to divide 169940 by 77.

Step 1:
1 divided by 77 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 77

Advancing to step 2:
77 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 77

On to step 3:
The number 77 fits into 169 2 times, leaving a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 154 from 169 leaves us with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 77

On to step 4:
When dividing 159 by 77, we get 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtracting 154 from 159 leaves us with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 77

Going ahead to step 5:
If we divide 54 by 77, we get 0 and a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 220.0
The remainder is 54 after subtracting 0 from 54.
Grab the next digit (0) from the dividend, add it to 54, then carry on: 540 / 77

Moving on to step 6:
When dividing 540 by 77, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 2207.0
If we take 539 away from 540, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
10 divided by 77 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 2207.0
Deduct 0 from 10 and we're left 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 8:
77 can be fit into 100 1 times, resulting in a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 2207.01
If we subtract 77 from 100, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
The number 77 fits into 230 2 times, leaving a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 2207.012
Subtracting 154 from 230 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 10:
The number 77 fits into 760 9 times, leaving a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 2207.0129
Subtracting 693 from 760 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 11:
77 goes into 670 8 times with a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 2207.01298
If we take 616 away from 670, we end up 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:
540 divided by 77 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 2207.012987
Subtract 539 from 540 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 13:
77 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 2207.012987
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.

Going ahead to step 14:
100 divided by 77 is 1 with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 2207.01298701
If we take 77 away from 100, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

After the division, we end up with 2207.01298701 and a remainder of 2.3e-08.
