We're dividing 31401109 by 143 
Let's see how many times 143 fits into 31401109.

Step 1:
If we divide 3 by 143, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 143

Going ahead to step 2:
The number 143 fits into 31 0 times, leaving a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Fetch the next digit (4) from the dividend, attach it to 31 and continue: 314 / 143

On to step 3:
143 goes into 314 2 times with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 286 from 314, we get 28.
Grab the next digit (0) from the dividend, add it to 28, then carry on: 280 / 143

Step 4:
When dividing 280 by 143, we get 1 with a remainder of 137.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtracting 143 from 280 leaves us with 137.
Bring next digit (1) of the dividend behind the 137 and repeat the process: 1371 / 143

On to step 5:
1371 divided by 143 is 9 with a remainder of 84.
Use 9 as the next digit of our solution. 
Result so far: 219.0
Subtracting 1287 from 1371 leaves us with 84.
Grab the next digit (1) from the dividend, add it to 84, then carry on: 841 / 143

Moving on to step 6:
The number 143 fits into 841 5 times, leaving a remainder of 126.
Write down 5 as next digit of the result. 
Result so far: 2195.0
The remainder is 126 after subtracting 715 from 841.
Include the next digit (0) from the dividend after 126, then repeat: 1260 / 143

Let's proceed to step 7:
1260 divided by 143 is 8 with a remainder of 116.
Write down 8 as next digit of the result. 
Result so far: 21958.0
If we take 1144 away from 1260, we end up with 116.
Bring next digit (9) of the dividend behind the 116 and repeat the process: 1169 / 143

Step 8:
1169 divided by 143 is 8 with a remainder of 25.
Record the quotient 8 as the next digit in the result. 
Result so far: 219588.0
If we subtract 1144 from 1169, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
The number 143 fits into 250 1 times, leaving a remainder of 107.
Use 1 as the next digit of our solution. 
Result so far: 219588.1
If we subtract 143 from 250, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Step 10:
143 goes into 1070 7 times with a remainder of 69.
Record the quotient 7 as the next digit in the result. 
Result so far: 219588.17
Deduct 1001 from 1070 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 11:
143 goes into 690 4 times with a remainder of 118.
Put 4 as the next digit of the answer. 
Result so far: 219588.174
If we take 572 away from 690, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 12:
When dividing 1180 by 143, we get 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 219588.1748
If we take 1144 away from 1180, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
The number 143 fits into 360 2 times, leaving a remainder of 74.
Record the quotient 2 as the next digit in the result. 
Result so far: 219588.17482
If we take 286 away from 360, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 14:
If we divide 740 by 143, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 219588.174825
If we take 715 away from 740, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 15:
If we divide 250 by 143, we get 1 and a remainder of 107.
Record the quotient 1 as the next digit in the result. 
Result so far: 219588.1748251
If we subtract 143 from 250, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Moving on to step 16:
143 can be fit into 1070 7 times, resulting in a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 219588.17482517
The remainder is 69 after subtracting 1001 from 1070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

The quotient of the division is 219588.17482517, and the remainder is 6.9e-08.
