35393143 ÷ 503 
Our goal is to divide 35393143 by 503.

Advancing to step 1:
The number 503 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 503

Moving on to step 2:
The number 503 fits into 35 0 times, leaving a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Fetch the next digit (3) from the dividend, attach it to 35 and continue: 353 / 503

On to step 3:
The number 503 fits into 353 0 times, leaving a remainder of 353.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 353 to get 353.
Append the next digit (9) from the dividend to 353 and continue with: 3539 / 503

Step 4:
503 goes into 3539 7 times with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 3521 from 3539 and we're left with 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 503

Moving on to step 5:
If we divide 183 by 503, we get 0 and a remainder of 183.
Put 0 as the next digit of the answer. 
Result so far: 70.0
If we subtract 0 from 183, we get 183.
Bring next digit (1) of the dividend behind the 183 and repeat the process: 1831 / 503

Advancing to step 6:
503 goes into 1831 3 times with a remainder of 322.
Use 3 as the next digit of our solution. 
Result so far: 703.0
Subtract 1509 from 1831 to get 322.
Bring next digit (4) of the dividend behind the 322 and repeat the process: 3224 / 503

Moving on to step 7:
The number 503 fits into 3224 6 times, leaving a remainder of 206.
Record the quotient 6 as the next digit in the result. 
Result so far: 7036.0
If we subtract 3018 from 3224, we get 206.
Fetch the next digit (3) from the dividend, attach it to 206 and continue: 2063 / 503

Let's proceed to step 8:
When dividing 2063 by 503, we get 4 with a remainder of 51.
Use 4 as the next digit of our solution. 
Result so far: 70364.0
If we subtract 2012 from 2063, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 9:
510 divided by 503 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 70364.1
Subtract 503 from 510 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
70 divided by 503 is 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 70364.1
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 11:
When dividing 700 by 503, we get 1 with a remainder of 197.
The next digit of our result is 1. 
Result so far: 70364.101
Subtract 503 from 700 to get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Moving on to step 12:
If we divide 1970 by 503, we get 3 and a remainder of 461.
Record the quotient 3 as the next digit in the result. 
Result so far: 70364.1013
Deduct 1509 from 1970 and we're left with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

On to step 13:
The number 503 fits into 4610 9 times, leaving a remainder of 83.
The number 9 becomes the next digit in our result. 
Result so far: 70364.10139
If we subtract 4527 from 4610, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 14:
503 goes into 830 1 times with a remainder of 327.
Write down 1 as next digit of the result. 
Result so far: 70364.101391
Deduct 503 from 830 and we're left with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Moving on to step 15:
503 goes into 3270 6 times with a remainder of 252.
The next digit of our result is 6. 
Result so far: 70364.1013916
The remainder is 252 after subtracting 3018 from 3270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 16:
503 goes into 2520 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 70364.10139165
Deduct 2515 from 2520 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 70364.10139165 and a remainder of 5e-09.
