42133398 ÷ 143 
We're looking to find how many times 143 goes into 42133398.

Let's proceed to step 1:
If we divide 4 by 143, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 143

Going ahead to step 2:
If we divide 42 by 143, we get 0 and a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 143

Step 3:
When dividing 421 by 143, we get 2 with a remainder of 135.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 286 from 421, we get 135.
Bring next digit (3) of the dividend behind the 135 and repeat the process: 1353 / 143

Let's proceed to step 4:
143 can be fit into 1353 9 times, resulting in a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Deduct 1287 from 1353 and we're left with 66.
Grab the next digit (3) from the dividend, add it to 66, then carry on: 663 / 143

Let's proceed to step 5:
663 divided by 143 is 4 with a remainder of 91.
Put 4 as the next digit of the answer. 
Result so far: 294.0
The remainder is 91 after subtracting 572 from 663.
Include the next digit (3) from the dividend after 91, then repeat: 913 / 143

Step 6:
143 can be fit into 913 6 times, resulting in a remainder of 55.
The number 6 becomes the next digit in our result. 
Result so far: 2946.0
Subtract 858 from 913 to get 55.
Bring next digit (9) of the dividend behind the 55 and repeat the process: 559 / 143

Step 7:
If we divide 559 by 143, we get 3 and a remainder of 130.
Write down 3 as next digit of the result. 
Result so far: 29463.0
If we take 429 away from 559, we end up with 130.
Include the next digit (8) from the dividend after 130, then repeat: 1308 / 143

Moving on to step 8:
If we divide 1308 by 143, we get 9 and a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 294639.0
Subtracting 1287 from 1308 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
When dividing 210 by 143, we get 1 with a remainder of 67.
Use 1 as the next digit of our solution. 
Result so far: 294639.1
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 10:
143 goes into 670 4 times with a remainder of 98.
The next digit of our result is 4. 
Result so far: 294639.14
If we subtract 572 from 670, we get 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 11:
The number 143 fits into 980 6 times, leaving a remainder of 122.
The number 6 becomes the next digit in our result. 
Result so far: 294639.146
If we subtract 858 from 980, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 12:
When dividing 1220 by 143, we get 8 with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 294639.1468
If we subtract 1144 from 1220, we get 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 13:
The number 143 fits into 760 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 294639.14685
If we take 715 away from 760, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 14:
143 can be fit into 450 3 times, resulting in a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 294639.146853
Subtract 429 from 450 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 15:
143 can be fit into 210 1 times, resulting in a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 294639.1468531
If we take 143 away from 210, 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.

Step 16:
143 goes into 670 4 times with a remainder of 98.
The number 4 becomes the next digit in our result. 
Result so far: 294639.14685314
If we subtract 572 from 670, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

After the division, we end up with 294639.14685314 and a remainder of 9.8e-08.
