83071421 ÷ 143 
We want to divide 83071421 by 143.

Moving on to step 1:
143 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 143

Let's proceed to step 2:
The number 143 fits into 83 0 times, leaving a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Append the next digit (0) from the dividend to 83 and continue with: 830 / 143

Let's proceed to step 3:
830 divided by 143 is 5 with a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 715 from 830 and we're left with 115.
Bring next digit (7) of the dividend behind the 115 and repeat the process: 1157 / 143

Let's proceed to step 4:
1157 divided by 143 is 8 with a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Subtracting 1144 from 1157 leaves us with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 143

On to step 5:
143 can be fit into 131 0 times, resulting in a remainder of 131.
Use 0 as the next digit of our solution. 
Result so far: 580.0
Subtracting 0 from 131 leaves us with 131.
Take the next digit (4) from the dividend and append it to 131, then repeat: 1314 / 143

On to step 6:
If we divide 1314 by 143, we get 9 and a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 5809.0
Subtracting 1287 from 1314 leaves us with 27.
Append the next digit (2) from the dividend to 27 and continue with: 272 / 143

Step 7:
When dividing 272 by 143, we get 1 with a remainder of 129.
The number 1 becomes the next digit in our result. 
Result so far: 58091.0
Subtract 143 from 272 to get 129.
Bring next digit (1) of the dividend behind the 129 and repeat the process: 1291 / 143

Advancing to step 8:
When dividing 1291 by 143, we get 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 580919.0
If we take 1287 away from 1291, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
40 divided by 143 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 580919.0
If we take 0 away from 40, we end up with 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 10:
143 can be fit into 400 2 times, resulting in a remainder of 114.
Put 2 as the next digit of the answer. 
Result so far: 580919.02
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.

Let's proceed to step 11:
The number 143 fits into 1140 7 times, leaving a remainder of 139.
Record the quotient 7 as the next digit in the result. 
Result so far: 580919.027
The remainder is 139 after subtracting 1001 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Going ahead to step 12:
If we divide 1390 by 143, we get 9 and a remainder of 103.
Write down 9 as next digit of the result. 
Result so far: 580919.0279
Subtracting 1287 from 1390 leaves us 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.

Going ahead to step 13:
When dividing 1030 by 143, we get 7 with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 580919.02797
Subtracting 1001 from 1030 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 14:
When dividing 290 by 143, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 580919.027972
Subtract 286 from 290 to 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.

Step 15:
143 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 580919.027972
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.

Moving on to step 16:
If we divide 400 by 143, we get 2 and a remainder of 114.
Use 2 as the next digit of our solution. 
Result so far: 580919.02797202
The remainder is 114 after subtracting 286 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

The final result is 580919.02797202 with a remainder of 1.14e-07.
