We look at the division of 552640 by 86 
We want to figure out the number of times 552640 can be divided by 86.

Advancing to step 1:
5 divided by 86 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 86

Moving on to step 2:
When dividing 55 by 86, we get 0 with a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Fetch the next digit (2) from the dividend, attach it to 55 and continue: 552 / 86

Step 3:
86 can be fit into 552 6 times, resulting in a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 516 away from 552, we end up with 36.
Take the next digit (6) from the dividend and append it to 36, then repeat: 366 / 86

Let's proceed to step 4:
If we divide 366 by 86, we get 4 and a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Subtract 344 from 366 to get 22.
Append the next digit (4) from the dividend to 22 and continue with: 224 / 86

Step 5:
When dividing 224 by 86, we get 2 with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 642.0
Subtracting 172 from 224 leaves us with 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 86

Moving on to step 6:
When dividing 520 by 86, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 6426.0
If we take 516 away from 520, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
86 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 6426.0
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
The number 86 fits into 400 4 times, leaving a remainder of 56.
The next digit of our result is 4. 
Result so far: 6426.04
Deduct 344 from 400 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
560 divided by 86 is 6 with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 6426.046
Subtracting 516 from 560 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
If we divide 440 by 86, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 6426.0465
If we subtract 430 from 440, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
The number 86 fits into 100 1 times, leaving a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 6426.04651
Subtract 86 from 100 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 12:
When dividing 140 by 86, we get 1 with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 6426.046511
If we subtract 86 from 140, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

In conclusion, the division gives 6426.046511 with a balance of 5.4e-06.
