Let's divide 639542 by 91
Our goal is to divide 639542 by 91.

Let's proceed to step 1:
The number 91 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 91

Step 2:
91 goes into 63 0 times with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 91

Advancing to step 3:
91 goes into 639 7 times with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 637 from 639 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 91

Step 4:
If we divide 25 by 91, we get 0 and a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
If we take 0 away from 25, we end up with 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 91

On to step 5:
91 goes into 254 2 times with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 702.0
Subtract 182 from 254 to get 72.
Bring next digit (2) of the dividend behind the 72 and repeat the process: 722 / 91

Advancing to step 6:
The number 91 fits into 722 7 times, leaving a remainder of 85.
Use 7 as the next digit of our solution. 
Result so far: 7027.0
If we take 637 away from 722, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 7:
91 can be fit into 850 9 times, resulting in a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 7027.9
Subtracting 819 from 850 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 8:
The number 91 fits into 310 3 times, leaving a remainder of 37.
The next digit of our result is 3. 
Result so far: 7027.93
If we subtract 273 from 310, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 9:
When dividing 370 by 91, we get 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 7027.934
Deduct 364 from 370 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
60 divided by 91 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 7027.934
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
91 can be fit into 600 6 times, resulting in a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 7027.93406
Subtracting 546 from 600 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 12:
540 divided by 91 is 5 with a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 7027.934065
The remainder is 85 after subtracting 455 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 13:
The number 91 fits into 850 9 times, leaving a remainder of 31.
The next digit of our result is 9. 
Result so far: 7027.9340659
If we subtract 819 from 850, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 14:
If we divide 310 by 91, we get 3 and a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 7027.93406593
If we take 273 away from 310, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The quotient of the division is 7027.93406593, and the remainder is 3.7e-08.
