We look at the division of 91681991 by 659 
Our goal is to divide 91681991 by 659.

Moving on to step 1:
659 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 659

Going ahead to step 2:
The number 659 fits into 91 0 times, leaving a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Take the next digit (6) from the dividend and append it to 91, then repeat: 916 / 659

Moving on to step 3:
If we divide 916 by 659, we get 1 and a remainder of 257.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 659 from 916 to get 257.
Include the next digit (8) from the dividend after 257, then repeat: 2578 / 659

Advancing to step 4:
When dividing 2578 by 659, we get 3 with a remainder of 601.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 1977 from 2578, we get 601.
Grab the next digit (1) from the dividend, add it to 601, then carry on: 6011 / 659

Advancing to step 5:
If we divide 6011 by 659, we get 9 and a remainder of 80.
Use 9 as the next digit of our solution. 
Result so far: 139.0
If we subtract 5931 from 6011, we get 80.
Grab the next digit (9) from the dividend, add it to 80, then carry on: 809 / 659

On to step 6:
The number 659 fits into 809 1 times, leaving a remainder of 150.
Record the quotient 1 as the next digit in the result. 
Result so far: 1391.0
If we subtract 659 from 809, we get 150.
Include the next digit (9) from the dividend after 150, then repeat: 1509 / 659

Let's proceed to step 7:
When dividing 1509 by 659, we get 2 with a remainder of 191.
The number 2 becomes the next digit in our result. 
Result so far: 13912.0
If we subtract 1318 from 1509, we get 191.
Append the next digit (1) from the dividend to 191 and continue with: 1911 / 659

Let's proceed to step 8:
1911 divided by 659 is 2 with a remainder of 593.
The next digit of our result is 2. 
Result so far: 139122.0
Subtract 1318 from 1911 to get 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

On to step 9:
659 goes into 5930 8 times with a remainder of 658.
The next digit of our result is 8. 
Result so far: 139122.8
Deduct 5272 from 5930 and we're left with 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Going ahead to step 10:
The number 659 fits into 6580 9 times, leaving a remainder of 649.
Record the quotient 9 as the next digit in the result. 
Result so far: 139122.89
Deduct 5931 from 6580 and we're left with 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

Advancing to step 11:
659 goes into 6490 9 times with a remainder of 559.
Write down 9 as next digit of the result. 
Result so far: 139122.899
Subtract 5931 from 6490 to get 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Our division results in 139122.899 with a remaining 0.0559.
