We look at the division of 86902172 by 654 
We want to figure out the number of times 86902172 can be divided by 654.

On to step 1:
If we divide 8 by 654, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 654

Advancing to step 2:
654 goes into 86 0 times with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Bring next digit (9) of the dividend behind the 86 and repeat the process: 869 / 654

Step 3:
654 goes into 869 1 times with a remainder of 215.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 654 from 869 and we're left with 215.
Append the next digit (0) from the dividend to 215 and continue with: 2150 / 654

Going ahead to step 4:
When dividing 2150 by 654, we get 3 with a remainder of 188.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 1962 away from 2150, we end up with 188.
Take the next digit (2) from the dividend and append it to 188, then repeat: 1882 / 654

On to step 5:
654 goes into 1882 2 times with a remainder of 574.
The number 2 becomes the next digit in our result. 
Result so far: 132.0
Subtracting 1308 from 1882 leaves us with 574.
Append the next digit (1) from the dividend to 574 and continue with: 5741 / 654

Advancing to step 6:
If we divide 5741 by 654, we get 8 and a remainder of 509.
The number 8 becomes the next digit in our result. 
Result so far: 1328.0
The remainder is 509 after subtracting 5232 from 5741.
Take the next digit (7) from the dividend and append it to 509, then repeat: 5097 / 654

Going ahead to step 7:
If we divide 5097 by 654, we get 7 and a remainder of 519.
The next digit of our result is 7. 
Result so far: 13287.0
If we take 4578 away from 5097, we end up with 519.
Grab the next digit (2) from the dividend, add it to 519, then carry on: 5192 / 654

Let's proceed to step 8:
If we divide 5192 by 654, we get 7 and a remainder of 614.
Record the quotient 7 as the next digit in the result. 
Result so far: 132877.0
Deduct 4578 from 5192 and we're left with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

On to step 9:
654 can be fit into 6140 9 times, resulting in a remainder of 254.
The number 9 becomes the next digit in our result. 
Result so far: 132877.9
The remainder is 254 after subtracting 5886 from 6140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Let's proceed to step 10:
654 goes into 2540 3 times with a remainder of 578.
Use 3 as the next digit of our solution. 
Result so far: 132877.93
Deduct 1962 from 2540 and we're left with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Advancing to step 11:
When dividing 5780 by 654, we get 8 with a remainder of 548.
Put 8 as the next digit of the answer. 
Result so far: 132877.938
If we subtract 5232 from 5780, we get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Advancing to step 12:
654 can be fit into 5480 8 times, resulting in a remainder of 248.
Record the quotient 8 as the next digit in the result. 
Result so far: 132877.9388
Deduct 5232 from 5480 and we're left 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 132877.9388 with a balance of 0.00248.
