Let's divide 551955 by 86
We want to figure out the number of times 551955 can be divided by 86.

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
If we subtract 0 from 5, we get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 86

On to step 2:
If we divide 55 by 86, we get 0 and a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Take the next digit (1) from the dividend and append it to 55, then repeat: 551 / 86

Advancing to step 3:
When dividing 551 by 86, we get 6 with a remainder of 35.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 516 from 551, we get 35.
Bring next digit (9) of the dividend behind the 35 and repeat the process: 359 / 86

Moving on to step 4:
If we divide 359 by 86, we get 4 and a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 64.0
Subtracting 344 from 359 leaves us with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 86

Advancing to step 5:
The number 86 fits into 155 1 times, leaving a remainder of 69.
The next digit of our result is 1. 
Result so far: 641.0
Deduct 86 from 155 and we're left with 69.
Bring next digit (5) of the dividend behind the 69 and repeat the process: 695 / 86

On to step 6:
The number 86 fits into 695 8 times, leaving a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 6418.0
The remainder is 7 after subtracting 688 from 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
The number 86 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 6418.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
86 goes into 700 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 6418.08
If we subtract 688 from 700, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
If we divide 120 by 86, we get 1 and a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 6418.081
Subtract 86 from 120 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
340 divided by 86 is 3 with a remainder of 82.
The next digit of our result is 3. 
Result so far: 6418.0813
Subtracting 258 from 340 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 11:
86 can be fit into 820 9 times, resulting in a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 6418.08139
Deduct 774 from 820 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
If we divide 460 by 86, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 6418.081395
Subtract 430 from 460 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
86 goes into 300 3 times with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 6418.0813953
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 14:
86 goes into 420 4 times with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 6418.08139534
If we subtract 344 from 420, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 6418.08139534, with a leftover of 7.6e-08.
