We look at the division of 77763909 by 169 
Our goal is to divide 77763909 by 169.

On to step 1:
The number 169 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 169

Going ahead to step 2:
169 goes into 77 0 times with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Bring next digit (7) of the dividend behind the 77 and repeat the process: 777 / 169

Let's proceed to step 3:
169 goes into 777 4 times with a remainder of 101.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 676 from 777 to get 101.
Bring next digit (6) of the dividend behind the 101 and repeat the process: 1016 / 169

Advancing to step 4:
1016 divided by 169 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 46.0
If we take 1014 away from 1016, we end up with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 169

Going ahead to step 5:
23 divided by 169 is 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 460.0
If we take 0 away from 23, we end up with 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 169

Let's proceed to step 6:
169 goes into 239 1 times with a remainder of 70.
The number 1 becomes the next digit in our result. 
Result so far: 4601.0
If we subtract 169 from 239, we get 70.
Take the next digit (0) from the dividend and append it to 70, then repeat: 700 / 169

Going ahead to step 7:
169 goes into 700 4 times with a remainder of 24.
The next digit of our result is 4. 
Result so far: 46014.0
If we subtract 676 from 700, we get 24.
Grab the next digit (9) from the dividend, add it to 24, then carry on: 249 / 169

On to step 8:
249 divided by 169 is 1 with a remainder of 80.
The number 1 becomes the next digit in our result. 
Result so far: 460141.0
Subtract 169 from 249 to get 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 9:
The number 169 fits into 800 4 times, leaving a remainder of 124.
Put 4 as the next digit of the answer. 
Result so far: 460141.4
If we take 676 away from 800, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 10:
169 goes into 1240 7 times with a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 460141.47
Subtract 1183 from 1240 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 11:
The number 169 fits into 570 3 times, leaving a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 460141.473
Subtract 507 from 570 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.

Step 12:
When dividing 630 by 169, we get 3 with a remainder of 123.
The number 3 becomes the next digit in our result. 
Result so far: 460141.4733
Deduct 507 from 630 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

The quotient of the division is 460141.4733, and the remainder is 0.00123.
