We look at the division of 90075851 by 664 
We want to figure out the number of times 90075851 can be divided by 664.

Moving on to step 1:
664 can be fit into 9 0 times, resulting in 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.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 664

Moving on to step 2:
When dividing 90 by 664, we get 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Bring next digit (0) of the dividend behind the 90 and repeat the process: 900 / 664

Advancing to step 3:
When dividing 900 by 664, we get 1 with a remainder of 236.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 664 from 900 leaves us with 236.
Grab the next digit (7) from the dividend, add it to 236, then carry on: 2367 / 664

Going ahead to step 4:
664 goes into 2367 3 times with a remainder of 375.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 1992 away from 2367, we end up with 375.
Fetch the next digit (5) from the dividend, attach it to 375 and continue: 3755 / 664

Step 5:
If we divide 3755 by 664, we get 5 and a remainder of 435.
Put 5 as the next digit of the answer. 
Result so far: 135.0
Subtracting 3320 from 3755 leaves us with 435.
Take the next digit (8) from the dividend and append it to 435, then repeat: 4358 / 664

On to step 6:
When dividing 4358 by 664, we get 6 with a remainder of 374.
Write down 6 as next digit of the result. 
Result so far: 1356.0
If we subtract 3984 from 4358, we get 374.
Take the next digit (5) from the dividend and append it to 374, then repeat: 3745 / 664

Step 7:
The number 664 fits into 3745 5 times, leaving a remainder of 425.
Put 5 as the next digit of the answer. 
Result so far: 13565.0
The remainder is 425 after subtracting 3320 from 3745.
Fetch the next digit (1) from the dividend, attach it to 425 and continue: 4251 / 664

Advancing to step 8:
The number 664 fits into 4251 6 times, leaving a remainder of 267.
Record the quotient 6 as the next digit in the result. 
Result so far: 135656.0
Subtracting 3984 from 4251 leaves us with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Going ahead to step 9:
664 can be fit into 2670 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 135656.4
Deduct 2656 from 2670 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
The number 664 fits into 140 0 times, leaving a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 135656.4
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 11:
1400 divided by 664 is 2 with a remainder of 72.
The next digit of our result is 2. 
Result so far: 135656.402
The remainder is 72 after subtracting 1328 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 12:
If we divide 720 by 664, we get 1 and a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 135656.4021
If we subtract 664 from 720, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 13:
The number 664 fits into 560 0 times, leaving a remainder of 560.
Write down 0 as next digit of the result. 
Result so far: 135656.4021
If we subtract 0 from 560, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 14:
If we divide 5600 by 664, we get 8 and a remainder of 288.
Use 8 as the next digit of our solution. 
Result so far: 135656.402108
Subtracting 5312 from 5600 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 15:
If we divide 2880 by 664, we get 4 and a remainder of 224.
The number 4 becomes the next digit in our result. 
Result so far: 135656.4021084
If we take 2656 away from 2880, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 16:
664 goes into 2240 3 times with a remainder of 248.
Use 3 as the next digit of our solution. 
Result so far: 135656.40210843
If we take 1992 away from 2240, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

In conclusion, the division gives 135656.40210843 with a balance of 2.48e-07.
