648645 divided by 86 
Our goal is to divide 648645 by 86.

Let's proceed to step 1:
6 divided by 86 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 86

Let's proceed to step 2:
If we divide 64 by 86, we get 0 and a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Grab the next digit (8) from the dividend, add it to 64, then carry on: 648 / 86

Moving on to step 3:
If we divide 648 by 86, we get 7 and a remainder of 46.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 602 away from 648, we end up with 46.
Bring next digit (6) of the dividend behind the 46 and repeat the process: 466 / 86

Advancing to step 4:
86 can be fit into 466 5 times, resulting in a remainder of 36.
Write down 5 as next digit of the result. 
Result so far: 75.0
If we subtract 430 from 466, we get 36.
Bring next digit (4) of the dividend behind the 36 and repeat the process: 364 / 86

Step 5:
364 divided by 86 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 754.0
Subtracting 344 from 364 leaves us with 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 86

Advancing to step 6:
205 divided by 86 is 2 with a remainder of 33.
The next digit of our result is 2. 
Result so far: 7542.0
The remainder is 33 after subtracting 172 from 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 7:
330 divided by 86 is 3 with a remainder of 72.
Use 3 as the next digit of our solution. 
Result so far: 7542.3
If we subtract 258 from 330, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 8:
86 goes into 720 8 times with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 7542.38
Subtract 688 from 720 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
86 goes into 320 3 times with a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 7542.383
If we take 258 away from 320, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 10:
When dividing 620 by 86, we get 7 with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 7542.3837
Deduct 602 from 620 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
The number 86 fits into 180 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 7542.38372
Subtract 172 from 180 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
If we divide 80 by 86, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 7542.38372
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
If we divide 800 by 86, we get 9 and a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 7542.3837209
Subtract 774 from 800 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 14:
The number 86 fits into 260 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 7542.38372093
If we subtract 258 from 260, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 7542.38372093 with a remaining 2e-09.
