We look at the division of 91309608 by 407 
We want to figure out the number of times 91309608 can be divided by 407.

Moving on to step 1:
407 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 407

On to step 2:
91 divided by 407 is 0 with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Take the next digit (3) from the dividend and append it to 91, then repeat: 913 / 407

Moving on to step 3:
407 can be fit into 913 2 times, resulting in a remainder of 99.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 814 from 913 to get 99.
Bring next digit (0) of the dividend behind the 99 and repeat the process: 990 / 407

Step 4:
407 goes into 990 2 times with a remainder of 176.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtracting 814 from 990 leaves us with 176.
Take the next digit (9) from the dividend and append it to 176, then repeat: 1769 / 407

Let's proceed to step 5:
1769 divided by 407 is 4 with a remainder of 141.
The number 4 becomes the next digit in our result. 
Result so far: 224.0
Subtract 1628 from 1769 to get 141.
Grab the next digit (6) from the dividend, add it to 141, then carry on: 1416 / 407

On to step 6:
When dividing 1416 by 407, we get 3 with a remainder of 195.
Put 3 as the next digit of the answer. 
Result so far: 2243.0
The remainder is 195 after subtracting 1221 from 1416.
Take the next digit (0) from the dividend and append it to 195, then repeat: 1950 / 407

Advancing to step 7:
1950 divided by 407 is 4 with a remainder of 322.
Use 4 as the next digit of our solution. 
Result so far: 22434.0
The remainder is 322 after subtracting 1628 from 1950.
Grab the next digit (8) from the dividend, add it to 322, then carry on: 3228 / 407

Moving on to step 8:
407 can be fit into 3228 7 times, resulting in a remainder of 379.
Put 7 as the next digit of the answer. 
Result so far: 224347.0
Deduct 2849 from 3228 and we're left with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Advancing to step 9:
407 can be fit into 3790 9 times, resulting in a remainder of 127.
Put 9 as the next digit of the answer. 
Result so far: 224347.9
Subtracting 3663 from 3790 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Let's proceed to step 10:
1270 divided by 407 is 3 with a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 224347.93
The remainder is 49 after subtracting 1221 from 1270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 11:
When dividing 490 by 407, we get 1 with a remainder of 83.
Put 1 as the next digit of the answer. 
Result so far: 224347.931
If we subtract 407 from 490, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 12:
830 divided by 407 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 224347.9312
The remainder is 16 after subtracting 814 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
160 divided by 407 is 0 with a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 224347.9312
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 14:
1600 divided by 407 is 3 with a remainder of 379.
Use 3 as the next digit of our solution. 
Result so far: 224347.931203
If we subtract 1221 from 1600, we get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

On to step 15:
If we divide 3790 by 407, we get 9 and a remainder of 127.
Record the quotient 9 as the next digit in the result. 
Result so far: 224347.9312039
If we take 3663 away from 3790, we end up with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 16:
If we divide 1270 by 407, we get 3 and a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 224347.93120393
Deduct 1221 from 1270 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final result is 224347.93120393 with a remainder of 4.9e-08.
