We're dividing 73147760 by 143 
We want to divide 73147760 by 143.

Advancing to step 1:
143 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 143

Going ahead to step 2:
When dividing 73 by 143, we get 0 with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Append the next digit (1) from the dividend to 73 and continue with: 731 / 143

Step 3:
143 goes into 731 5 times with a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 715 from 731 and we're left with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 143

Moving on to step 4:
164 divided by 143 is 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 51.0
If we take 143 away from 164, we end up with 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 143

On to step 5:
143 can be fit into 217 1 times, resulting in a remainder of 74.
Put 1 as the next digit of the answer. 
Result so far: 511.0
If we take 143 away from 217, we end up with 74.
Append the next digit (7) from the dividend to 74 and continue with: 747 / 143

Let's proceed to step 6:
747 divided by 143 is 5 with a remainder of 32.
The number 5 becomes the next digit in our result. 
Result so far: 5115.0
The remainder is 32 after subtracting 715 from 747.
Bring next digit (6) of the dividend behind the 32 and repeat the process: 326 / 143

Let's proceed to step 7:
143 can be fit into 326 2 times, resulting in a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 51152.0
Subtract 286 from 326 to get 40.
Include the next digit (0) from the dividend after 40, then repeat: 400 / 143

Let's proceed to step 8:
The number 143 fits into 400 2 times, leaving a remainder of 114.
Record the quotient 2 as the next digit in the result. 
Result so far: 511522.0
If we subtract 286 from 400, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 9:
The number 143 fits into 1140 7 times, leaving a remainder of 139.
The number 7 becomes the next digit in our result. 
Result so far: 511522.7
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.

Step 10:
When dividing 1390 by 143, we get 9 with a remainder of 103.
The next digit of our result is 9. 
Result so far: 511522.79
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.

Going ahead to step 11:
If we divide 1030 by 143, we get 7 and a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 511522.797
Deduct 1001 from 1030 and we're left 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.

Let's proceed to step 12:
290 divided by 143 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 511522.7972
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.

Going ahead to step 13:
143 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 511522.7972
If we subtract 0 from 40, we get 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 14:
143 goes into 400 2 times with a remainder of 114.
Write down 2 as next digit of the result. 
Result so far: 511522.797202
Subtract 286 from 400 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 15:
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: 511522.7972027
Subtract 1001 from 1140 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Let's proceed to step 16:
When dividing 1390 by 143, we get 9 with a remainder of 103.
The number 9 becomes the next digit in our result. 
Result so far: 511522.79720279
The remainder is 103 after subtracting 1287 from 1390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

The final result is 511522.79720279 with a remainder of 1.03e-07.
