Let's divide 643762 by 87
Our goal is to divide 643762 by 87.

Let's proceed to step 1:
If we divide 6 by 87, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 87

Let's proceed to step 2:
64 divided by 87 is 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Fetch the next digit (3) from the dividend, attach it to 64 and continue: 643 / 87

Step 3:
87 goes into 643 7 times with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 609 from 643 leaves us with 34.
Take the next digit (7) from the dividend and append it to 34, then repeat: 347 / 87

Moving on to step 4:
347 divided by 87 is 3 with a remainder of 86.
Put 3 as the next digit of the answer. 
Result so far: 73.0
If we take 261 away from 347, we end up with 86.
Append the next digit (6) from the dividend to 86 and continue with: 866 / 87

Going ahead to step 5:
The number 87 fits into 866 9 times, leaving a remainder of 83.
The number 9 becomes the next digit in our result. 
Result so far: 739.0
Subtracting 783 from 866 leaves us with 83.
Include the next digit (2) from the dividend after 83, then repeat: 832 / 87

On to step 6:
87 goes into 832 9 times with a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 7399.0
Subtract 783 from 832 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 7:
490 divided by 87 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 7399.5
If we subtract 435 from 490, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 8:
87 can be fit into 550 6 times, resulting in a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 7399.56
Subtract 522 from 550 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
87 goes into 280 3 times with a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 7399.563
If we subtract 261 from 280, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 10:
The number 87 fits into 190 2 times, leaving a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 7399.5632
The remainder is 16 after subtracting 174 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
The number 87 fits into 160 1 times, leaving a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 7399.56321
If we subtract 87 from 160, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 12:
87 can be fit into 730 8 times, resulting in a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 7399.563218
Subtract 696 from 730 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 13:
87 goes into 340 3 times with a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 7399.5632183
Subtracting 261 from 340 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 14:
The number 87 fits into 790 9 times, leaving a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 7399.56321839
The remainder is 7 after subtracting 783 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 7399.56321839, with a leftover of 7e-09.
