We look at the division of 91620359 by 671 
We want to figure out the number of times 91620359 can be divided by 671.

Moving on to step 1:
9 divided by 671 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 671

Moving on to step 2:
671 can be fit into 91 0 times, resulting in a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Append the next digit (6) from the dividend to 91 and continue with: 916 / 671

Step 3:
If we divide 916 by 671, we get 1 and a remainder of 245.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 671 from 916 and we're left with 245.
Include the next digit (2) from the dividend after 245, then repeat: 2452 / 671

On to step 4:
When dividing 2452 by 671, we get 3 with a remainder of 439.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 439 after subtracting 2013 from 2452.
Include the next digit (0) from the dividend after 439, then repeat: 4390 / 671

Let's proceed to step 5:
671 goes into 4390 6 times with a remainder of 364.
Use 6 as the next digit of our solution. 
Result so far: 136.0
Subtracting 4026 from 4390 leaves us with 364.
Include the next digit (3) from the dividend after 364, then repeat: 3643 / 671

Moving on to step 6:
3643 divided by 671 is 5 with a remainder of 288.
Record the quotient 5 as the next digit in the result. 
Result so far: 1365.0
The remainder is 288 after subtracting 3355 from 3643.
Grab the next digit (5) from the dividend, add it to 288, then carry on: 2885 / 671

On to step 7:
When dividing 2885 by 671, we get 4 with a remainder of 201.
Record the quotient 4 as the next digit in the result. 
Result so far: 13654.0
If we subtract 2684 from 2885, we get 201.
Grab the next digit (9) from the dividend, add it to 201, then carry on: 2019 / 671

Let's proceed to step 8:
The number 671 fits into 2019 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 136543.0
Subtracting 2013 from 2019 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
When dividing 60 by 671, we get 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 136543.0
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
671 can be fit into 600 0 times, resulting in a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 136543.0
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final outcome is 136543.0, with a leftover of 0.6.
