87499097 ÷ 669 
We want to divide 87499097 by 669.

Step 1:
669 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 669

Moving on to step 2:
If we divide 87 by 669, we get 0 and a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Append the next digit (4) from the dividend to 87 and continue with: 874 / 669

Going ahead to step 3:
If we divide 874 by 669, we get 1 and a remainder of 205.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 669 from 874 and we're left with 205.
Take the next digit (9) from the dividend and append it to 205, then repeat: 2059 / 669

Step 4:
2059 divided by 669 is 3 with a remainder of 52.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 2007 from 2059 and we're left with 52.
Fetch the next digit (9) from the dividend, attach it to 52 and continue: 529 / 669

Advancing to step 5:
669 goes into 529 0 times with a remainder of 529.
Use 0 as the next digit of our solution. 
Result so far: 130.0
If we take 0 away from 529, we end up with 529.
Grab the next digit (0) from the dividend, add it to 529, then carry on: 5290 / 669

Advancing to step 6:
669 goes into 5290 7 times with a remainder of 607.
The number 7 becomes the next digit in our result. 
Result so far: 1307.0
If we take 4683 away from 5290, we end up with 607.
Fetch the next digit (9) from the dividend, attach it to 607 and continue: 6079 / 669

Step 7:
669 goes into 6079 9 times with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 13079.0
Deduct 6021 from 6079 and we're left with 58.
Fetch the next digit (7) from the dividend, attach it to 58 and continue: 587 / 669

On to step 8:
When dividing 587 by 669, we get 0 with a remainder of 587.
Put 0 as the next digit of the answer. 
Result so far: 130790.0
Subtract 0 from 587 to get 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Going ahead to step 9:
The number 669 fits into 5870 8 times, leaving a remainder of 518.
Write down 8 as next digit of the result. 
Result so far: 130790.8
Deduct 5352 from 5870 and we're left with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Moving on to step 10:
669 goes into 5180 7 times with a remainder of 497.
The next digit of our result is 7. 
Result so far: 130790.87
If we take 4683 away from 5180, we end up with 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Step 11:
669 can be fit into 4970 7 times, resulting in a remainder of 287.
The number 7 becomes the next digit in our result. 
Result so far: 130790.877
The remainder is 287 after subtracting 4683 from 4970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

In conclusion, the division gives 130790.877 with a balance of 0.0287.
