We're dividing 669495 by 400 
Our goal is to divide 669495 by 400.

Let's proceed to step 1:
The number 400 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 400

Step 2:
66 divided by 400 is 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Take the next digit (9) from the dividend and append it to 66, then repeat: 669 / 400

Advancing to step 3:
When dividing 669 by 400, we get 1 with a remainder of 269.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 400 from 669 and we're left with 269.
Fetch the next digit (4) from the dividend, attach it to 269 and continue: 2694 / 400

On to step 4:
2694 divided by 400 is 6 with a remainder of 294.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 2400 away from 2694, we end up with 294.
Grab the next digit (9) from the dividend, add it to 294, then carry on: 2949 / 400

Step 5:
2949 divided by 400 is 7 with a remainder of 149.
Use 7 as the next digit of our solution. 
Result so far: 167.0
Subtracting 2800 from 2949 leaves us with 149.
Bring next digit (5) of the dividend behind the 149 and repeat the process: 1495 / 400

Going ahead to step 6:
400 can be fit into 1495 3 times, resulting in a remainder of 295.
The number 3 becomes the next digit in our result. 
Result so far: 1673.0
The remainder is 295 after subtracting 1200 from 1495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 7:
400 can be fit into 2950 7 times, resulting in a remainder of 150.
The next digit of our result is 7. 
Result so far: 1673.7
Subtract 2800 from 2950 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 8:
When dividing 1500 by 400, we get 3 with a remainder of 300.
Record the quotient 3 as the next digit in the result. 
Result so far: 1673.73
If we subtract 1200 from 1500, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 9:
If we divide 3000 by 400, we get 7 and a remainder of 200.
Record the quotient 7 as the next digit in the result. 
Result so far: 1673.737
If we take 2800 away from 3000, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 10:
When dividing 2000 by 400, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1673.7375
Subtracting 2000 from 2000 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
If we divide 0 by 400, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1673.7375
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
If we divide 0 by 400, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1673.7375
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 1673.7375 and a remainder of 0.0.
