Let's divide 73930145 by 87
We want to divide 73930145 by 87.

Step 1:
87 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 87

Step 2:
73 divided by 87 is 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Fetch the next digit (9) from the dividend, attach it to 73 and continue: 739 / 87

Step 3:
739 divided by 87 is 8 with a remainder of 43.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 696 from 739 to get 43.
Take the next digit (3) from the dividend and append it to 43, then repeat: 433 / 87

Advancing to step 4:
87 can be fit into 433 4 times, resulting in a remainder of 85.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
The remainder is 85 after subtracting 348 from 433.
Grab the next digit (0) from the dividend, add it to 85, then carry on: 850 / 87

Going ahead to step 5:
850 divided by 87 is 9 with a remainder of 67.
Write down 9 as next digit of the result. 
Result so far: 849.0
Subtract 783 from 850 to get 67.
Fetch the next digit (1) from the dividend, attach it to 67 and continue: 671 / 87

Going ahead to step 6:
87 goes into 671 7 times with a remainder of 62.
The next digit of our result is 7. 
Result so far: 8497.0
If we take 609 away from 671, we end up with 62.
Append the next digit (4) from the dividend to 62 and continue with: 624 / 87

Advancing to step 7:
87 goes into 624 7 times with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 84977.0
Subtract 609 from 624 to get 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 87

Advancing to step 8:
87 can be fit into 155 1 times, resulting in a remainder of 68.
The next digit of our result is 1. 
Result so far: 849771.0
The remainder is 68 after subtracting 87 from 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 9:
The number 87 fits into 680 7 times, leaving a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 849771.7
If we subtract 609 from 680, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 10:
If we divide 710 by 87, we get 8 and a remainder of 14.
The next digit of our result is 8. 
Result so far: 849771.78
If we take 696 away from 710, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
The number 87 fits into 140 1 times, leaving a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 849771.781
If we take 87 away from 140, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 12:
The number 87 fits into 530 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 849771.7816
Subtracting 522 from 530 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.

Advancing to step 13:
The number 87 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 849771.7816
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
If we divide 800 by 87, we get 9 and a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 849771.781609
Subtract 783 from 800 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 15:
The number 87 fits into 170 1 times, leaving a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 849771.7816091
If we take 87 away from 170, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 16:
If we divide 830 by 87, we get 9 and a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 849771.78160919
Deduct 783 from 830 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final result is 849771.78160919 with a remainder of 4.7e-08.
