We look at the division of 77690478 by 669 
Let's see how many times 669 fits into 77690478.

Let's proceed to step 1:
When dividing 7 by 669, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 669

On to step 2:
77 divided by 669 is 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Bring next digit (6) of the dividend behind the 77 and repeat the process: 776 / 669

Step 3:
669 goes into 776 1 times with a remainder of 107.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 669 from 776 leaves us with 107.
Include the next digit (9) from the dividend after 107, then repeat: 1079 / 669

Step 4:
The number 669 fits into 1079 1 times, leaving a remainder of 410.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 669 from 1079 and we're left with 410.
Append the next digit (0) from the dividend to 410 and continue with: 4100 / 669

Step 5:
If we divide 4100 by 669, we get 6 and a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
Subtracting 4014 from 4100 leaves us with 86.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 669

Step 6:
The number 669 fits into 864 1 times, leaving a remainder of 195.
Record the quotient 1 as the next digit in the result. 
Result so far: 1161.0
The remainder is 195 after subtracting 669 from 864.
Include the next digit (7) from the dividend after 195, then repeat: 1957 / 669

Going ahead to step 7:
1957 divided by 669 is 2 with a remainder of 619.
Write down 2 as next digit of the result. 
Result so far: 11612.0
Subtract 1338 from 1957 to get 619.
Append the next digit (8) from the dividend to 619 and continue with: 6198 / 669

Moving on to step 8:
669 can be fit into 6198 9 times, resulting in a remainder of 177.
Write down 9 as next digit of the result. 
Result so far: 116129.0
If we subtract 6021 from 6198, we get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Going ahead to step 9:
When dividing 1770 by 669, we get 2 with a remainder of 432.
The number 2 becomes the next digit in our result. 
Result so far: 116129.2
The remainder is 432 after subtracting 1338 from 1770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Going ahead to step 10:
4320 divided by 669 is 6 with a remainder of 306.
The number 6 becomes the next digit in our result. 
Result so far: 116129.26
If we take 4014 away from 4320, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 11:
If we divide 3060 by 669, we get 4 and a remainder of 384.
Record the quotient 4 as the next digit in the result. 
Result so far: 116129.264
Subtracting 2676 from 3060 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 12:
When dividing 3840 by 669, we get 5 with a remainder of 495.
Use 5 as the next digit of our solution. 
Result so far: 116129.2645
The remainder is 495 after subtracting 3345 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Advancing to step 13:
669 can be fit into 4950 7 times, resulting in a remainder of 267.
Use 7 as the next digit of our solution. 
Result so far: 116129.26457
The remainder is 267 after subtracting 4683 from 4950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Step 14:
669 goes into 2670 3 times with a remainder of 663.
The number 3 becomes the next digit in our result. 
Result so far: 116129.264573
The remainder is 663 after subtracting 2007 from 2670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Let's proceed to step 15:
669 goes into 6630 9 times with a remainder of 609.
Use 9 as the next digit of our solution. 
Result so far: 116129.2645739
Deduct 6021 from 6630 and we're left with 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Moving on to step 16:
669 goes into 6090 9 times with a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 116129.26457399
Subtract 6021 from 6090 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

The final outcome is 116129.26457399, with a leftover of 6.9e-08.
