143390 divided by 76 
We want to figure out the number of times 143390 can be divided by 76.

Going ahead to step 1:
1 divided by 76 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 76

Moving on to step 2:
14 divided by 76 is 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 76

Step 3:
143 divided by 76 is 1 with a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 76 from 143, we get 67.
Grab the next digit (3) from the dividend, add it to 67, then carry on: 673 / 76

Let's proceed to step 4:
76 can be fit into 673 8 times, resulting in a remainder of 65.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtract 608 from 673 to get 65.
Include the next digit (9) from the dividend after 65, then repeat: 659 / 76

On to step 5:
76 goes into 659 8 times with a remainder of 51.
Put 8 as the next digit of the answer. 
Result so far: 188.0
Subtracting 608 from 659 leaves us with 51.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 76

Moving on to step 6:
510 divided by 76 is 6 with a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 1886.0
If we subtract 456 from 510, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 7:
76 can be fit into 540 7 times, resulting in a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 1886.7
Subtracting 532 from 540 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
When dividing 80 by 76, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1886.71
The remainder is 4 after subtracting 76 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
When dividing 40 by 76, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 1886.71
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.

Let's proceed to step 10:
If we divide 400 by 76, we get 5 and a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 1886.7105
Subtracting 380 from 400 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
200 divided by 76 is 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 1886.71052
If we subtract 152 from 200, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 12:
When dividing 480 by 76, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 1886.710526
If we subtract 456 from 480, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
If we divide 240 by 76, we get 3 and a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 1886.7105263
If we take 228 away from 240, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
When dividing 120 by 76, we get 1 with a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 1886.71052631
Deduct 76 from 120 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 1886.71052631 and a remainder of 4.4e-08.
