We look at the division of 551651 by 86 
Our goal is to divide 551651 by 86.

Advancing to step 1:
When dividing 5 by 86, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 86

Moving on to step 2:
When dividing 55 by 86, we get 0 with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Fetch the next digit (1) from the dividend, attach it to 55 and continue: 551 / 86

Let's proceed to step 3:
If we divide 551 by 86, we get 6 and a remainder of 35.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 516 from 551 to get 35.
Fetch the next digit (6) from the dividend, attach it to 35 and continue: 356 / 86

Step 4:
The number 86 fits into 356 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Subtracting 344 from 356 leaves us with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 86

Step 5:
86 can be fit into 125 1 times, resulting in a remainder of 39.
The next digit of our result is 1. 
Result so far: 641.0
Subtracting 86 from 125 leaves us with 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 86

Step 6:
391 divided by 86 is 4 with a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 6414.0
The remainder is 47 after subtracting 344 from 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 7:
If we divide 470 by 86, we get 5 and a remainder of 40.
The next digit of our result is 5. 
Result so far: 6414.5
Deduct 430 from 470 and we're left 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:
400 divided by 86 is 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 6414.54
If we subtract 344 from 400, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
When dividing 560 by 86, we get 6 with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 6414.546
Deduct 516 from 560 and we're left 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:
86 goes into 440 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 6414.5465
Deduct 430 from 440 and we're left with 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:
86 can be fit into 100 1 times, resulting in a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 6414.54651
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
140 divided by 86 is 1 with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 6414.546511
Subtracting 86 from 140 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 6414.546511 with a remainder of 5.4e-06.
