31524703 ÷ 143 
We want to figure out the number of times 31524703 can be divided by 143.

On to step 1:
3 divided by 143 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 143

On to step 2:
If we divide 31 by 143, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 143

On to step 3:
If we divide 315 by 143, we get 2 and a remainder of 29.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 286 from 315, we get 29.
Grab the next digit (2) from the dividend, add it to 29, then carry on: 292 / 143

Moving on to step 4:
292 divided by 143 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 286 from 292 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 143

On to step 5:
143 goes into 64 0 times with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 220.0
If we take 0 away from 64, we end up with 64.
Append the next digit (7) from the dividend to 64 and continue with: 647 / 143

Let's proceed to step 6:
If we divide 647 by 143, we get 4 and a remainder of 75.
Write down 4 as next digit of the result. 
Result so far: 2204.0
Subtract 572 from 647 to get 75.
Take the next digit (0) from the dividend and append it to 75, then repeat: 750 / 143

Going ahead to step 7:
When dividing 750 by 143, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 22045.0
Deduct 715 from 750 and we're left with 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 143

Advancing to step 8:
143 goes into 353 2 times with a remainder of 67.
Write down 2 as next digit of the result. 
Result so far: 220452.0
If we take 286 away from 353, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 9:
When dividing 670 by 143, we get 4 with a remainder of 98.
Use 4 as the next digit of our solution. 
Result so far: 220452.4
The remainder is 98 after subtracting 572 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 10:
143 goes into 980 6 times with a remainder of 122.
Put 6 as the next digit of the answer. 
Result so far: 220452.46
Deduct 858 from 980 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 11:
The number 143 fits into 1220 8 times, leaving a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 220452.468
If we take 1144 away from 1220, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 12:
The number 143 fits into 760 5 times, leaving a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 220452.4685
If we subtract 715 from 760, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 13:
When dividing 450 by 143, we get 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 220452.46853
The remainder is 21 after subtracting 429 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 14:
143 goes into 210 1 times with a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 220452.468531
If we subtract 143 from 210, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 15:
143 can be fit into 670 4 times, resulting in a remainder of 98.
Record the quotient 4 as the next digit in the result. 
Result so far: 220452.4685314
If we take 572 away from 670, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 16:
When dividing 980 by 143, we get 6 with a remainder of 122.
Use 6 as the next digit of our solution. 
Result so far: 220452.46853146
The remainder is 122 after subtracting 858 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

The quotient of the division is 220452.46853146, and the remainder is 1.22e-07.
