Let's divide 621625 by 86
Our goal is to divide 621625 by 86.

Advancing to step 1:
If we divide 6 by 86, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 86

On to step 2:
62 divided by 86 is 0 with a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 62, we get 62.
Append the next digit (1) from the dividend to 62 and continue with: 621 / 86

Let's proceed to step 3:
If we divide 621 by 86, we get 7 and a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 602 from 621 and we're left with 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 86

Going ahead to step 4:
If we divide 196 by 86, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Subtracting 172 from 196 leaves us with 24.
Fetch the next digit (2) from the dividend, attach it to 24 and continue: 242 / 86

Moving on to step 5:
The number 86 fits into 242 2 times, leaving a remainder of 70.
Use 2 as the next digit of our solution. 
Result so far: 722.0
Subtracting 172 from 242 leaves us with 70.
Fetch the next digit (5) from the dividend, attach it to 70 and continue: 705 / 86

Going ahead to step 6:
When dividing 705 by 86, we get 8 with a remainder of 17.
The next digit of our result is 8. 
Result so far: 7228.0
Deduct 688 from 705 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
170 divided by 86 is 1 with a remainder of 84.
Put 1 as the next digit of the answer. 
Result so far: 7228.1
The remainder is 84 after subtracting 86 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 8:
86 can be fit into 840 9 times, resulting in a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 7228.19
The remainder is 66 after subtracting 774 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 9:
86 goes into 660 7 times with a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 7228.197
Subtracting 602 from 660 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 10:
If we divide 580 by 86, we get 6 and a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 7228.1976
Deduct 516 from 580 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 11:
The number 86 fits into 640 7 times, leaving a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 7228.19767
The remainder is 38 after subtracting 602 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
The number 86 fits into 380 4 times, leaving a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 7228.197674
If we take 344 away from 380, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
86 can be fit into 360 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 7228.1976744
Deduct 344 from 360 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 7228.1976744 and a remainder of 1.6e-07.
