We're dividing 90104254 by 653 
We want to figure out the number of times 90104254 can be divided by 653.

Advancing to step 1:
The number 653 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 653

Let's proceed to step 2:
The number 653 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Grab the next digit (1) from the dividend, add it to 90, then carry on: 901 / 653

Advancing to step 3:
653 goes into 901 1 times with a remainder of 248.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 653 from 901, we get 248.
Fetch the next digit (0) from the dividend, attach it to 248 and continue: 2480 / 653

Going ahead to step 4:
When dividing 2480 by 653, we get 3 with a remainder of 521.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1959 from 2480 leaves us with 521.
Grab the next digit (4) from the dividend, add it to 521, then carry on: 5214 / 653

Step 5:
5214 divided by 653 is 7 with a remainder of 643.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
Subtract 4571 from 5214 to get 643.
Include the next digit (2) from the dividend after 643, then repeat: 6432 / 653

Step 6:
653 can be fit into 6432 9 times, resulting in a remainder of 555.
Put 9 as the next digit of the answer. 
Result so far: 1379.0
Subtract 5877 from 6432 to get 555.
Grab the next digit (5) from the dividend, add it to 555, then carry on: 5555 / 653

On to step 7:
653 goes into 5555 8 times with a remainder of 331.
Write down 8 as next digit of the result. 
Result so far: 13798.0
Deduct 5224 from 5555 and we're left with 331.
Include the next digit (4) from the dividend after 331, then repeat: 3314 / 653

Advancing to step 8:
The number 653 fits into 3314 5 times, leaving a remainder of 49.
Write down 5 as next digit of the result. 
Result so far: 137985.0
Subtracting 3265 from 3314 leaves us 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.

Going ahead to step 9:
490 divided by 653 is 0 with a remainder of 490.
The number 0 becomes the next digit in our result. 
Result so far: 137985.0
The remainder is 490 after subtracting 0 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Step 10:
653 can be fit into 4900 7 times, resulting in a remainder of 329.
The number 7 becomes the next digit in our result. 
Result so far: 137985.07
The remainder is 329 after subtracting 4571 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Advancing to step 11:
653 goes into 3290 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 137985.075
Deduct 3265 from 3290 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 12:
The number 653 fits into 250 0 times, leaving a remainder of 250.
The next digit of our result is 0. 
Result so far: 137985.075
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 13:
2500 divided by 653 is 3 with a remainder of 541.
Put 3 as the next digit of the answer. 
Result so far: 137985.07503
If we take 1959 away from 2500, we end up with 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Step 14:
653 goes into 5410 8 times with a remainder of 186.
Write down 8 as next digit of the result. 
Result so far: 137985.075038
If we take 5224 away from 5410, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 15:
653 can be fit into 1860 2 times, resulting in a remainder of 554.
Write down 2 as next digit of the result. 
Result so far: 137985.0750382
Subtract 1306 from 1860 to get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Step 16:
When dividing 5540 by 653, we get 8 with a remainder of 316.
Use 8 as the next digit of our solution. 
Result so far: 137985.07503828
The remainder is 316 after subtracting 5224 from 5540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

The final result is 137985.07503828 with a remainder of 3.16e-07.
