We divide 621641 by 86
We want to figure out the number of times 621641 can be divided by 86.

Going ahead to step 1:
When dividing 6 by 86, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 86

Let's proceed to step 2:
62 divided by 86 is 0 with a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Take the next digit (1) from the dividend and append it to 62, then repeat: 621 / 86

Moving on to step 3:
86 can be fit into 621 7 times, resulting in a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 19 after subtracting 602 from 621.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 86

On to step 4:
196 divided by 86 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 72.0
Subtracting 172 from 196 leaves us with 24.
Fetch the next digit (4) from the dividend, attach it to 24 and continue: 244 / 86

Let's proceed to step 5:
244 divided by 86 is 2 with a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 722.0
If we take 172 away from 244, we end up with 72.
Take the next digit (1) from the dividend and append it to 72, then repeat: 721 / 86

Step 6:
The number 86 fits into 721 8 times, leaving a remainder of 33.
The next digit of our result is 8. 
Result so far: 7228.0
Deduct 688 from 721 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 7:
86 can be fit into 330 3 times, resulting in a remainder of 72.
The next digit of our result is 3. 
Result so far: 7228.3
The remainder is 72 after subtracting 258 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 8:
86 can be fit into 720 8 times, resulting in a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 7228.38
The remainder is 32 after subtracting 688 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
When dividing 320 by 86, we get 3 with a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 7228.383
Subtract 258 from 320 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to 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: 7228.3837
Subtract 602 from 620 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 11:
The number 86 fits into 180 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 7228.38372
If we take 172 away from 180, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
The number 86 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 7228.38372
If we subtract 0 from 80, we get 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:
800 divided by 86 is 9 with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 7228.3837209
The remainder is 26 after subtracting 774 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
86 goes into 260 3 times with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 7228.38372093
Deduct 258 from 260 and we're left with 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 7228.38372093 with a remaining 2e-09.
