We divide 668690 by 91
Our goal is to divide 668690 by 91.

Moving on to step 1:
91 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 91

On to step 2:
91 goes into 66 0 times with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Take the next digit (8) from the dividend and append it to 66, then repeat: 668 / 91

Let's proceed to step 3:
When dividing 668 by 91, we get 7 with a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 31 after subtracting 637 from 668.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 91

On to step 4:
When dividing 316 by 91, we get 3 with a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 73.0
The remainder is 43 after subtracting 273 from 316.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 91

Going ahead to step 5:
The number 91 fits into 439 4 times, leaving a remainder of 75.
Record the quotient 4 as the next digit in the result. 
Result so far: 734.0
The remainder is 75 after subtracting 364 from 439.
Include the next digit (0) from the dividend after 75, then repeat: 750 / 91

Advancing to step 6:
750 divided by 91 is 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 7348.0
Subtract 728 from 750 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
91 can be fit into 220 2 times, resulting in a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 7348.2
Deduct 182 from 220 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
91 goes into 380 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 7348.24
Subtracting 364 from 380 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
The number 91 fits into 160 1 times, leaving a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 7348.241
Deduct 91 from 160 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 10:
91 can be fit into 690 7 times, resulting in a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 7348.2417
Subtracting 637 from 690 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 11:
530 divided by 91 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 7348.24175
Subtracting 455 from 530 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 12:
When dividing 750 by 91, we get 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 7348.241758
If we take 728 away from 750, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
If we divide 220 by 91, we get 2 and a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 7348.2417582
The remainder is 38 after subtracting 182 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 14:
The number 91 fits into 380 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 7348.24175824
Subtract 364 from 380 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 7348.24175824 with a remainder of 1.6e-08.
