Let's divide 671868 by 91
We want to figure out the number of times 671868 can be divided by 91.

Step 1:
If we divide 6 by 91, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 91

Let's proceed to step 2:
91 goes into 67 0 times with a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Fetch the next digit (1) from the dividend, attach it to 67 and continue: 671 / 91

Step 3:
91 can be fit into 671 7 times, resulting in a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 637 from 671 leaves us with 34.
Include the next digit (8) from the dividend after 34, then repeat: 348 / 91

Going ahead to step 4:
If we divide 348 by 91, we get 3 and a remainder of 75.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
The remainder is 75 after subtracting 273 from 348.
Append the next digit (6) from the dividend to 75 and continue with: 756 / 91

On to step 5:
756 divided by 91 is 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 738.0
If we subtract 728 from 756, we get 28.
Include the next digit (8) from the dividend after 28, then repeat: 288 / 91

Step 6:
91 can be fit into 288 3 times, resulting in a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 7383.0
Subtract 273 from 288 to 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.

Let's proceed to step 7:
When dividing 150 by 91, we get 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 7383.1
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.

Step 8:
91 goes into 590 6 times with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 7383.16
Subtract 546 from 590 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
When dividing 440 by 91, we get 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 7383.164
If we take 364 away from 440, we end up with 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 10:
760 divided by 91 is 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 7383.1648
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.

Advancing to step 11:
When dividing 320 by 91, we get 3 with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 7383.16483
Deduct 273 from 320 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.

Let's proceed to step 12:
91 can be fit into 470 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 7383.164835
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.

Let's proceed to step 13:
When dividing 150 by 91, we get 1 with a remainder of 59.
The next digit of our result is 1. 
Result so far: 7383.1648351
The remainder is 59 after subtracting 91 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 14:
When dividing 590 by 91, we get 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 7383.16483516
If we take 546 away from 590, we end up 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.

The final result is 7383.16483516 with a remainder of 4.4e-08.
