77403861 divided by 669 
We're looking to find how many times 669 goes into 77403861.

Step 1:
7 divided by 669 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 669

Let's proceed to step 2:
The number 669 fits into 77 0 times, leaving a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Append the next digit (4) from the dividend to 77 and continue with: 774 / 669

Let's proceed to step 3:
669 goes into 774 1 times with a remainder of 105.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 669 from 774 to get 105.
Fetch the next digit (0) from the dividend, attach it to 105 and continue: 1050 / 669

Moving on to step 4:
669 can be fit into 1050 1 times, resulting in a remainder of 381.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 669 from 1050 to get 381.
Bring next digit (3) of the dividend behind the 381 and repeat the process: 3813 / 669

Moving on to step 5:
The number 669 fits into 3813 5 times, leaving a remainder of 468.
The next digit of our result is 5. 
Result so far: 115.0
If we take 3345 away from 3813, we end up with 468.
Append the next digit (8) from the dividend to 468 and continue with: 4688 / 669

Going ahead to step 6:
669 goes into 4688 7 times with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 1157.0
Subtract 4683 from 4688 to get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 669

On to step 7:
669 can be fit into 56 0 times, resulting in a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 11570.0
If we subtract 0 from 56, we get 56.
Take the next digit (1) from the dividend and append it to 56, then repeat: 561 / 669

Step 8:
When dividing 561 by 669, we get 0 with a remainder of 561.
Use 0 as the next digit of our solution. 
Result so far: 115700.0
If we take 0 away from 561, we end up with 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Step 9:
If we divide 5610 by 669, we get 8 and a remainder of 258.
Put 8 as the next digit of the answer. 
Result so far: 115700.8
The remainder is 258 after subtracting 5352 from 5610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Step 10:
If we divide 2580 by 669, we get 3 and a remainder of 573.
Use 3 as the next digit of our solution. 
Result so far: 115700.83
If we subtract 2007 from 2580, we get 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Moving on to step 11:
The number 669 fits into 5730 8 times, leaving a remainder of 378.
Write down 8 as next digit of the result. 
Result so far: 115700.838
Subtracting 5352 from 5730 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Going ahead to step 12:
669 can be fit into 3780 5 times, resulting in a remainder of 435.
Put 5 as the next digit of the answer. 
Result so far: 115700.8385
Subtracting 3345 from 3780 leaves us with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Step 13:
669 can be fit into 4350 6 times, resulting in a remainder of 336.
Use 6 as the next digit of our solution. 
Result so far: 115700.83856
If we take 4014 away from 4350, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 14:
669 can be fit into 3360 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 115700.838565
Deduct 3345 from 3360 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 15:
When dividing 150 by 669, we get 0 with a remainder of 150.
The next digit of our result is 0. 
Result so far: 115700.838565
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 16:
If we divide 1500 by 669, we get 2 and a remainder of 162.
Write down 2 as next digit of the result. 
Result so far: 115700.83856502
The remainder is 162 after subtracting 1338 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

The final result is 115700.83856502 with a remainder of 1.62e-07.
