Let's divide 90736123 by 669
We're looking to find how many times 669 goes into 90736123.

On to step 1:
The number 669 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 669

Let's proceed to step 2:
669 can be fit into 90 0 times, resulting in a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Take the next digit (7) from the dividend and append it to 90, then repeat: 907 / 669

Advancing to step 3:
If we divide 907 by 669, we get 1 and a remainder of 238.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 669 from 907 to get 238.
Bring next digit (3) of the dividend behind the 238 and repeat the process: 2383 / 669

Moving on to step 4:
669 can be fit into 2383 3 times, resulting in a remainder of 376.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 2007 from 2383 to get 376.
Append the next digit (6) from the dividend to 376 and continue with: 3766 / 669

Advancing to step 5:
When dividing 3766 by 669, we get 5 with a remainder of 421.
Put 5 as the next digit of the answer. 
Result so far: 135.0
If we subtract 3345 from 3766, we get 421.
Include the next digit (1) from the dividend after 421, then repeat: 4211 / 669

Let's proceed to step 6:
669 can be fit into 4211 6 times, resulting in a remainder of 197.
The number 6 becomes the next digit in our result. 
Result so far: 1356.0
Subtract 4014 from 4211 to get 197.
Fetch the next digit (2) from the dividend, attach it to 197 and continue: 1972 / 669

On to step 7:
669 can be fit into 1972 2 times, resulting in a remainder of 634.
Use 2 as the next digit of our solution. 
Result so far: 13562.0
If we subtract 1338 from 1972, we get 634.
Append the next digit (3) from the dividend to 634 and continue with: 6343 / 669

Let's proceed to step 8:
669 goes into 6343 9 times with a remainder of 322.
Put 9 as the next digit of the answer. 
Result so far: 135629.0
The remainder is 322 after subtracting 6021 from 6343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

On to step 9:
The number 669 fits into 3220 4 times, leaving a remainder of 544.
The next digit of our result is 4. 
Result so far: 135629.4
Deduct 2676 from 3220 and we're left with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Moving on to step 10:
5440 divided by 669 is 8 with a remainder of 88.
Put 8 as the next digit of the answer. 
Result so far: 135629.48
If we take 5352 away from 5440, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 11:
When dividing 880 by 669, we get 1 with a remainder of 211.
Put 1 as the next digit of the answer. 
Result so far: 135629.481
If we take 669 away from 880, we end up with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Step 12:
669 can be fit into 2110 3 times, resulting in a remainder of 103.
Put 3 as the next digit of the answer. 
Result so far: 135629.4813
The remainder is 103 after subtracting 2007 from 2110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 13:
The number 669 fits into 1030 1 times, leaving a remainder of 361.
Write down 1 as next digit of the result. 
Result so far: 135629.48131
If we take 669 away from 1030, we end up with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Going ahead to step 14:
If we divide 3610 by 669, we get 5 and a remainder of 265.
Use 5 as the next digit of our solution. 
Result so far: 135629.481315
Deduct 3345 from 3610 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 15:
2650 divided by 669 is 3 with a remainder of 643.
The next digit of our result is 3. 
Result so far: 135629.4813153
Subtracting 2007 from 2650 leaves us with 643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

Going ahead to step 16:
If we divide 6430 by 669, we get 9 and a remainder of 409.
The next digit of our result is 9. 
Result so far: 135629.48131539
If we subtract 6021 from 6430, we get 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

The quotient of the division is 135629.48131539, and the remainder is 4.09e-07.
