We divide 669404 by 91
We want to figure out the number of times 669404 can be divided by 91.

Going ahead to step 1:
91 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 91

Going ahead to step 2:
If we divide 66 by 91, we get 0 and a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 91

Let's proceed to step 3:
When dividing 669 by 91, we get 7 with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 637 from 669 to get 32.
Take the next digit (4) from the dividend and append it to 32, then repeat: 324 / 91

Let's proceed to step 4:
The number 91 fits into 324 3 times, leaving a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 73.0
If we subtract 273 from 324, we get 51.
Take the next digit (0) from the dividend and append it to 51, then repeat: 510 / 91

Advancing to step 5:
The number 91 fits into 510 5 times, leaving a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 735.0
If we take 455 away from 510, we end up with 55.
Include the next digit (4) from the dividend after 55, then repeat: 554 / 91

On to step 6:
The number 91 fits into 554 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 7356.0
If we take 546 away from 554, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
91 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 7356.0
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 8:
When dividing 800 by 91, we get 8 with a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 7356.08
Subtracting 728 from 800 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 9:
91 can be fit into 720 7 times, resulting in a remainder of 83.
The number 7 becomes the next digit in our result. 
Result so far: 7356.087
The remainder is 83 after subtracting 637 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 10:
If we divide 830 by 91, we get 9 and a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 7356.0879
If we take 819 away from 830, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 11:
110 divided by 91 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 7356.08791
Subtracting 91 from 110 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 12:
190 divided by 91 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 7356.087912
If we take 182 away from 190, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
The number 91 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 7356.087912
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 14:
If we divide 800 by 91, we get 8 and a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 7356.08791208
If we subtract 728 from 800, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 7356.08791208, and the remainder is 7.2e-08.
