We look at the division of 90372209 by 688 
We want to figure out the number of times 90372209 can be divided by 688.

Moving on to step 1:
When dividing 9 by 688, we get 0 with 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 / 688

Step 2:
688 goes into 90 0 times with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Take the next digit (3) from the dividend and append it to 90, then repeat: 903 / 688

Going ahead to step 3:
When dividing 903 by 688, we get 1 with a remainder of 215.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 215 after subtracting 688 from 903.
Grab the next digit (7) from the dividend, add it to 215, then carry on: 2157 / 688

On to step 4:
2157 divided by 688 is 3 with a remainder of 93.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 2064 from 2157 leaves us with 93.
Bring next digit (2) of the dividend behind the 93 and repeat the process: 932 / 688

Going ahead to step 5:
932 divided by 688 is 1 with a remainder of 244.
Write down 1 as next digit of the result. 
Result so far: 131.0
Subtracting 688 from 932 leaves us with 244.
Grab the next digit (2) from the dividend, add it to 244, then carry on: 2442 / 688

Moving on to step 6:
When dividing 2442 by 688, we get 3 with a remainder of 378.
Record the quotient 3 as the next digit in the result. 
Result so far: 1313.0
If we take 2064 away from 2442, we end up with 378.
Fetch the next digit (0) from the dividend, attach it to 378 and continue: 3780 / 688

Moving on to step 7:
The number 688 fits into 3780 5 times, leaving a remainder of 340.
The number 5 becomes the next digit in our result. 
Result so far: 13135.0
If we subtract 3440 from 3780, we get 340.
Grab the next digit (9) from the dividend, add it to 340, then carry on: 3409 / 688

Going ahead to step 8:
When dividing 3409 by 688, we get 4 with a remainder of 657.
Use 4 as the next digit of our solution. 
Result so far: 131354.0
Subtract 2752 from 3409 to get 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Advancing to step 9:
The number 688 fits into 6570 9 times, leaving a remainder of 378.
Put 9 as the next digit of the answer. 
Result so far: 131354.9
Subtract 6192 from 6570 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Let's proceed to step 10:
3780 divided by 688 is 5 with a remainder of 340.
Record the quotient 5 as the next digit in the result. 
Result so far: 131354.95
Deduct 3440 from 3780 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 11:
688 goes into 3400 4 times with a remainder of 648.
Put 4 as the next digit of the answer. 
Result so far: 131354.954
The remainder is 648 after subtracting 2752 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Going ahead to step 12:
6480 divided by 688 is 9 with a remainder of 288.
Put 9 as the next digit of the answer. 
Result so far: 131354.9549
Subtract 6192 from 6480 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 13:
When dividing 2880 by 688, we get 4 with a remainder of 128.
Write down 4 as next digit of the result. 
Result so far: 131354.95494
If we take 2752 away from 2880, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 14:
The number 688 fits into 1280 1 times, leaving a remainder of 592.
Write down 1 as next digit of the result. 
Result so far: 131354.954941
If we take 688 away from 1280, we end up with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Moving on to step 15:
5920 divided by 688 is 8 with a remainder of 416.
Use 8 as the next digit of our solution. 
Result so far: 131354.9549418
If we subtract 5504 from 5920, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 16:
688 goes into 4160 6 times with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 131354.95494186
Deduct 4128 from 4160 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 131354.95494186 with a balance of 3.2e-08.
