91478674 ÷ 891 
We want to figure out the number of times 91478674 can be divided by 891.

Step 1:
891 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 891

Step 2:
891 can be fit into 91 0 times, resulting in a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Bring next digit (4) of the dividend behind the 91 and repeat the process: 914 / 891

Going ahead to step 3:
891 can be fit into 914 1 times, resulting in a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 891 away from 914, we end up with 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 891

Moving on to step 4:
The number 891 fits into 237 0 times, leaving a remainder of 237.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 237 and we're left with 237.
Bring next digit (8) of the dividend behind the 237 and repeat the process: 2378 / 891

Step 5:
891 can be fit into 2378 2 times, resulting in a remainder of 596.
Write down 2 as next digit of the result. 
Result so far: 102.0
The remainder is 596 after subtracting 1782 from 2378.
Include the next digit (6) from the dividend after 596, then repeat: 5966 / 891

Moving on to step 6:
5966 divided by 891 is 6 with a remainder of 620.
The next digit of our result is 6. 
Result so far: 1026.0
Deduct 5346 from 5966 and we're left with 620.
Append the next digit (7) from the dividend to 620 and continue with: 6207 / 891

Advancing to step 7:
If we divide 6207 by 891, we get 6 and a remainder of 861.
Write down 6 as next digit of the result. 
Result so far: 10266.0
Deduct 5346 from 6207 and we're left with 861.
Bring next digit (4) of the dividend behind the 861 and repeat the process: 8614 / 891

Advancing to step 8:
When dividing 8614 by 891, we get 9 with a remainder of 595.
Put 9 as the next digit of the answer. 
Result so far: 102669.0
If we take 8019 away from 8614, we end up with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

On to step 9:
5950 divided by 891 is 6 with a remainder of 604.
Record the quotient 6 as the next digit in the result. 
Result so far: 102669.6
Subtracting 5346 from 5950 leaves us with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Let's proceed to step 10:
The number 891 fits into 6040 6 times, leaving a remainder of 694.
The next digit of our result is 6. 
Result so far: 102669.66
The remainder is 694 after subtracting 5346 from 6040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

The final outcome is 102669.66, with a leftover of 0.694.
