We're dividing 689432 by 91 
We want to figure out the number of times 689432 can be divided by 91.

Step 1:
6 divided by 91 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 91

Advancing to step 2:
68 divided by 91 is 0 with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Append the next digit (9) from the dividend to 68 and continue with: 689 / 91

Moving on to step 3:
91 goes into 689 7 times with a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 637 from 689 to get 52.
Include the next digit (4) from the dividend after 52, then repeat: 524 / 91

On to step 4:
The number 91 fits into 524 5 times, leaving a remainder of 69.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
If we take 455 away from 524, we end up with 69.
Include the next digit (3) from the dividend after 69, then repeat: 693 / 91

Let's proceed to step 5:
91 goes into 693 7 times with a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 757.0
The remainder is 56 after subtracting 637 from 693.
Include the next digit (2) from the dividend after 56, then repeat: 562 / 91

Step 6:
91 can be fit into 562 6 times, resulting in a remainder of 16.
The next digit of our result is 6. 
Result so far: 7576.0
Deduct 546 from 562 and we're left 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.

Let's proceed to step 7:
160 divided by 91 is 1 with a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 7576.1
If we subtract 91 from 160, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 8:
690 divided by 91 is 7 with a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 7576.17
If we subtract 637 from 690, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 9:
91 goes into 530 5 times with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 7576.175
Subtract 455 from 530 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 10:
91 can be fit into 750 8 times, resulting in a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 7576.1758
Deduct 728 from 750 and we're left 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.

Let's proceed to step 11:
The number 91 fits into 220 2 times, leaving a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 7576.17582
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 12:
91 can be fit into 380 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 7576.175824
If we subtract 364 from 380, we 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.

Moving on to step 13:
160 divided by 91 is 1 with a remainder of 69.
The next digit of our result is 1. 
Result so far: 7576.1758241
The remainder is 69 after subtracting 91 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 14:
The number 91 fits into 690 7 times, leaving a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 7576.17582417
Deduct 637 from 690 and we're left 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.

Our division results in 7576.17582417 with a remaining 5.3e-08.
