91432381 divided by 672 
We want to figure out the number of times 91432381 can be divided by 672.

Step 1:
If we divide 9 by 672, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 672

Moving on to step 2:
The number 672 fits into 91 0 times, leaving a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Take the next digit (4) from the dividend and append it to 91, then repeat: 914 / 672

Step 3:
914 divided by 672 is 1 with a remainder of 242.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 672 from 914 to get 242.
Append the next digit (3) from the dividend to 242 and continue with: 2423 / 672

Advancing to step 4:
672 goes into 2423 3 times with a remainder of 407.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 2016 from 2423 leaves us with 407.
Grab the next digit (2) from the dividend, add it to 407, then carry on: 4072 / 672

Advancing to step 5:
672 can be fit into 4072 6 times, resulting in a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 136.0
Subtracting 4032 from 4072 leaves us with 40.
Append the next digit (3) from the dividend to 40 and continue with: 403 / 672

Going ahead to step 6:
672 can be fit into 403 0 times, resulting in a remainder of 403.
Write down 0 as next digit of the result. 
Result so far: 1360.0
Subtracting 0 from 403 leaves us with 403.
Bring next digit (8) of the dividend behind the 403 and repeat the process: 4038 / 672

On to step 7:
4038 divided by 672 is 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 13606.0
Subtract 4032 from 4038 to get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 672

Let's proceed to step 8:
The number 672 fits into 61 0 times, leaving a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 136060.0
Deduct 0 from 61 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 9:
When dividing 610 by 672, we get 0 with a remainder of 610.
Use 0 as the next digit of our solution. 
Result so far: 136060.0
If we take 0 away from 610, we end up with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Advancing to step 10:
6100 divided by 672 is 9 with a remainder of 52.
Put 9 as the next digit of the answer. 
Result so far: 136060.09
If we subtract 6048 from 6100, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
When dividing 520 by 672, we get 0 with a remainder of 520.
Record the quotient 0 as the next digit in the result. 
Result so far: 136060.09
If we take 0 away from 520, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 12:
672 goes into 5200 7 times with a remainder of 496.
Record the quotient 7 as the next digit in the result. 
Result so far: 136060.0907
If we take 4704 away from 5200, we end up with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 13:
When dividing 4960 by 672, we get 7 with a remainder of 256.
Use 7 as the next digit of our solution. 
Result so far: 136060.09077
Deduct 4704 from 4960 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

After the division, we end up with 136060.09077 and a remainder of 0.000256.
