We're dividing 670909 by 91 
We want to figure out the number of times 670909 can be divided by 91.

Going ahead to step 1:
6 divided by 91 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 91

Moving on to step 2:
91 goes into 67 0 times with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Bring next digit (0) of the dividend behind the 67 and repeat the process: 670 / 91

Let's proceed to step 3:
91 can be fit into 670 7 times, resulting in a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 637 from 670 to get 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 91

Moving on to step 4:
91 goes into 339 3 times with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 73.0
Deduct 273 from 339 and we're left with 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 91

Moving on to step 5:
91 can be fit into 660 7 times, resulting in a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 737.0
Subtract 637 from 660 to get 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 91

Let's proceed to step 6:
If we divide 239 by 91, we get 2 and a remainder of 57.
Put 2 as the next digit of the answer. 
Result so far: 7372.0
Subtract 182 from 239 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 7:
91 goes into 570 6 times with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 7372.6
The remainder is 24 after subtracting 546 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
If we divide 240 by 91, we get 2 and a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 7372.62
Deduct 182 from 240 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 9:
91 can be fit into 580 6 times, resulting in a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 7372.626
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
91 can be fit into 340 3 times, resulting in a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 7372.6263
If we subtract 273 from 340, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 11:
If we divide 670 by 91, we get 7 and a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 7372.62637
Deduct 637 from 670 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 12:
91 goes into 330 3 times with a remainder of 57.
The next digit of our result is 3. 
Result so far: 7372.626373
Subtract 273 from 330 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 13:
If we divide 570 by 91, we get 6 and a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 7372.6263736
If we subtract 546 from 570, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 14:
240 divided by 91 is 2 with a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 7372.62637362
Deduct 182 from 240 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The quotient of the division is 7372.62637362, and the remainder is 5.8e-08.
