Let's divide 642583 by 91
We want to figure out the number of times 642583 can be divided by 91.

Going ahead to step 1:
6 divided by 91 is 0 with 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.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 91

Going ahead to step 2:
The number 91 fits into 64 0 times, leaving a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Fetch the next digit (2) from the dividend, attach it to 64 and continue: 642 / 91

Moving on to step 3:
When dividing 642 by 91, we get 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 637 from 642, we get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 91

Advancing to step 4:
When dividing 55 by 91, we get 0 with a remainder of 55.
The next digit of our result is 0. 
Result so far: 70.0
If we subtract 0 from 55, we get 55.
Bring next digit (8) of the dividend behind the 55 and repeat the process: 558 / 91

Let's proceed to step 5:
If we divide 558 by 91, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 706.0
The remainder is 12 after subtracting 546 from 558.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 91

Moving on to step 6:
91 goes into 123 1 times with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 7061.0
Subtract 91 from 123 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
If we divide 320 by 91, we get 3 and a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 7061.3
If we take 273 away from 320, we end up 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.

Moving on to step 8:
91 goes into 470 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 7061.35
If we subtract 455 from 470, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
150 divided by 91 is 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 7061.351
Subtracting 91 from 150 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 10:
91 can be fit into 590 6 times, resulting in a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 7061.3516
The remainder is 44 after subtracting 546 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
91 goes into 440 4 times with a remainder of 76.
The next digit of our result is 4. 
Result so far: 7061.35164
Subtract 364 from 440 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 12:
The number 91 fits into 760 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 7061.351648
If we take 728 away from 760, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 13:
When dividing 320 by 91, we get 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 7061.3516483
Subtracting 273 from 320 leaves us 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.

Moving on to step 14:
470 divided by 91 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 7061.35164835
Subtracting 455 from 470 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 7061.35164835 with a remaining 1.5e-08.
