31609824 divided by 143 
We want to figure out the number of times 31609824 can be divided by 143.

Let's proceed to step 1:
143 can be fit into 3 0 times, resulting in 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.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 143

Let's proceed to step 2:
The number 143 fits into 31 0 times, leaving a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 143

Moving on to step 3:
143 goes into 316 2 times with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 30 after subtracting 286 from 316.
Include the next digit (0) from the dividend after 30, then repeat: 300 / 143

Going ahead to step 4:
If we divide 300 by 143, we get 2 and a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we subtract 286 from 300, we get 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 143

On to step 5:
The number 143 fits into 149 1 times, leaving a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 221.0
The remainder is 6 after subtracting 143 from 149.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 143

Step 6:
The number 143 fits into 68 0 times, leaving a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 2210.0
The remainder is 68 after subtracting 0 from 68.
Bring next digit (2) of the dividend behind the 68 and repeat the process: 682 / 143

On to step 7:
682 divided by 143 is 4 with a remainder of 110.
Put 4 as the next digit of the answer. 
Result so far: 22104.0
Deduct 572 from 682 and we're left with 110.
Append the next digit (4) from the dividend to 110 and continue with: 1104 / 143

On to step 8:
If we divide 1104 by 143, we get 7 and a remainder of 103.
The next digit of our result is 7. 
Result so far: 221047.0
If we take 1001 away from 1104, we end up with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 9:
143 goes into 1030 7 times with a remainder of 29.
The next digit of our result is 7. 
Result so far: 221047.7
Subtract 1001 from 1030 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 10:
If we divide 290 by 143, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 221047.72
If we subtract 286 from 290, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
143 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 221047.72
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
400 divided by 143 is 2 with a remainder of 114.
Write down 2 as next digit of the result. 
Result so far: 221047.7202
Deduct 286 from 400 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 13:
When dividing 1140 by 143, we get 7 with a remainder of 139.
Write down 7 as next digit of the result. 
Result so far: 221047.72027
If we take 1001 away from 1140, we end up with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Moving on to step 14:
1390 divided by 143 is 9 with a remainder of 103.
The next digit of our result is 9. 
Result so far: 221047.720279
Deduct 1287 from 1390 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Step 15:
1030 divided by 143 is 7 with a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 221047.7202797
The remainder is 29 after subtracting 1001 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 16:
143 goes into 290 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 221047.72027972
The remainder is 4 after subtracting 286 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 221047.72027972, with a leftover of 4e-09.
