We look at the division of 69644340 by 503 
Let's see how many times 503 fits into 69644340.

Moving on to step 1:
If we divide 6 by 503, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 503

Moving on to step 2:
If we divide 69 by 503, we get 0 and a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Append the next digit (6) from the dividend to 69 and continue with: 696 / 503

Advancing to step 3:
The number 503 fits into 696 1 times, leaving a remainder of 193.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 503 from 696 leaves us with 193.
Grab the next digit (4) from the dividend, add it to 193, then carry on: 1934 / 503

Going ahead to step 4:
When dividing 1934 by 503, we get 3 with a remainder of 425.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1509 from 1934 leaves us with 425.
Grab the next digit (4) from the dividend, add it to 425, then carry on: 4254 / 503

Step 5:
503 can be fit into 4254 8 times, resulting in a remainder of 230.
Put 8 as the next digit of the answer. 
Result so far: 138.0
If we take 4024 away from 4254, we end up with 230.
Bring next digit (3) of the dividend behind the 230 and repeat the process: 2303 / 503

On to step 6:
2303 divided by 503 is 4 with a remainder of 291.
Put 4 as the next digit of the answer. 
Result so far: 1384.0
Deduct 2012 from 2303 and we're left with 291.
Fetch the next digit (4) from the dividend, attach it to 291 and continue: 2914 / 503

On to step 7:
If we divide 2914 by 503, we get 5 and a remainder of 399.
The next digit of our result is 5. 
Result so far: 13845.0
Subtracting 2515 from 2914 leaves us with 399.
Grab the next digit (0) from the dividend, add it to 399, then carry on: 3990 / 503

Advancing to step 8:
3990 divided by 503 is 7 with a remainder of 469.
Put 7 as the next digit of the answer. 
Result so far: 138457.0
Deduct 3521 from 3990 and we're left with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Step 9:
503 goes into 4690 9 times with a remainder of 163.
The number 9 becomes the next digit in our result. 
Result so far: 138457.9
If we take 4527 away from 4690, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Moving on to step 10:
503 can be fit into 1630 3 times, resulting in a remainder of 121.
The number 3 becomes the next digit in our result. 
Result so far: 138457.93
Subtracting 1509 from 1630 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Going ahead to step 11:
503 can be fit into 1210 2 times, resulting in a remainder of 204.
Use 2 as the next digit of our solution. 
Result so far: 138457.932
If we subtract 1006 from 1210, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 12:
2040 divided by 503 is 4 with a remainder of 28.
The next digit of our result is 4. 
Result so far: 138457.9324
If we take 2012 away from 2040, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
280 divided by 503 is 0 with a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 138457.9324
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 14:
When dividing 2800 by 503, we get 5 with a remainder of 285.
Record the quotient 5 as the next digit in the result. 
Result so far: 138457.932405
Subtracting 2515 from 2800 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 15:
503 goes into 2850 5 times with a remainder of 335.
Record the quotient 5 as the next digit in the result. 
Result so far: 138457.9324055
If we take 2515 away from 2850, we end up with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Our division results in 138457.9324055 with a remaining 3.35e-06.
