We divide 12577231 by 669
Our goal is to divide 12577231 by 669.

Going ahead to step 1:
The number 669 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 669

Step 2:
669 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 669

Let's proceed to step 3:
125 divided by 669 is 0 with a remainder of 125.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 125 and we're left with 125.
Bring next digit (7) of the dividend behind the 125 and repeat the process: 1257 / 669

On to step 4:
1257 divided by 669 is 1 with a remainder of 588.
The next digit of our result is 1. 
Result so far: 1.0
If we take 669 away from 1257, we end up with 588.
Grab the next digit (7) from the dividend, add it to 588, then carry on: 5887 / 669

Going ahead to step 5:
669 goes into 5887 8 times with a remainder of 535.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we take 5352 away from 5887, we end up with 535.
Take the next digit (2) from the dividend and append it to 535, then repeat: 5352 / 669

Advancing to step 6:
If we divide 5352 by 669, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 188.0
If we take 5352 away from 5352, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 669

On to step 7:
669 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 1880.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 669

Let's proceed to step 8:
The number 669 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 18800.0
Deduct 0 from 31 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
669 can be fit into 310 0 times, resulting in a remainder of 310.
Record the quotient 0 as the next digit in the result. 
Result so far: 18800.0
Deduct 0 from 310 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 10:
When dividing 3100 by 669, we get 4 with a remainder of 424.
The number 4 becomes the next digit in our result. 
Result so far: 18800.04
Deduct 2676 from 3100 and we're left with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Let's proceed to step 11:
When dividing 4240 by 669, we get 6 with a remainder of 226.
The number 6 becomes the next digit in our result. 
Result so far: 18800.046
If we subtract 4014 from 4240, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 12:
669 can be fit into 2260 3 times, resulting in a remainder of 253.
The number 3 becomes the next digit in our result. 
Result so far: 18800.0463
Subtracting 2007 from 2260 leaves us with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Moving on to step 13:
669 goes into 2530 3 times with a remainder of 523.
Put 3 as the next digit of the answer. 
Result so far: 18800.04633
If we subtract 2007 from 2530, we get 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

The quotient of the division is 18800.04633, and the remainder is 0.000523.
