91669405 ÷ 407 
Our goal is to divide 91669405 by 407.

Moving on to step 1:
9 divided by 407 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 407

Step 2:
91 divided by 407 is 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Fetch the next digit (6) from the dividend, attach it to 91 and continue: 916 / 407

On to step 3:
916 divided by 407 is 2 with a remainder of 102.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 814 from 916, we get 102.
Append the next digit (6) from the dividend to 102 and continue with: 1026 / 407

Step 4:
The number 407 fits into 1026 2 times, leaving a remainder of 212.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we take 814 away from 1026, we end up with 212.
Take the next digit (9) from the dividend and append it to 212, then repeat: 2129 / 407

On to step 5:
2129 divided by 407 is 5 with a remainder of 94.
Write down 5 as next digit of the result. 
Result so far: 225.0
If we take 2035 away from 2129, we end up with 94.
Bring next digit (4) of the dividend behind the 94 and repeat the process: 944 / 407

Moving on to step 6:
407 goes into 944 2 times with a remainder of 130.
The number 2 becomes the next digit in our result. 
Result so far: 2252.0
If we subtract 814 from 944, we get 130.
Bring next digit (0) of the dividend behind the 130 and repeat the process: 1300 / 407

Let's proceed to step 7:
When dividing 1300 by 407, we get 3 with a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 22523.0
Deduct 1221 from 1300 and we're left with 79.
Include the next digit (5) from the dividend after 79, then repeat: 795 / 407

Moving on to step 8:
407 can be fit into 795 1 times, resulting in a remainder of 388.
Use 1 as the next digit of our solution. 
Result so far: 225231.0
Deduct 407 from 795 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 9:
407 goes into 3880 9 times with a remainder of 217.
Put 9 as the next digit of the answer. 
Result so far: 225231.9
The remainder is 217 after subtracting 3663 from 3880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Advancing to step 10:
The number 407 fits into 2170 5 times, leaving a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 225231.95
If we take 2035 away from 2170, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 11:
407 can be fit into 1350 3 times, resulting in a remainder of 129.
The number 3 becomes the next digit in our result. 
Result so far: 225231.953
Subtracting 1221 from 1350 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Going ahead to step 12:
When dividing 1290 by 407, we get 3 with a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 225231.9533
If we subtract 1221 from 1290, 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.

The quotient of the division is 225231.9533, and the remainder is 0.00069.
