We're dividing 86520376 by 622 
We want to figure out the number of times 86520376 can be divided by 622.

Step 1:
8 divided by 622 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 622

Let's proceed to step 2:
If we divide 86 by 622, we get 0 and a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Include the next digit (5) from the dividend after 86, then repeat: 865 / 622

On to step 3:
When dividing 865 by 622, we get 1 with a remainder of 243.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 243 after subtracting 622 from 865.
Include the next digit (2) from the dividend after 243, then repeat: 2432 / 622

Going ahead to step 4:
622 goes into 2432 3 times with a remainder of 566.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 566 after subtracting 1866 from 2432.
Bring next digit (0) of the dividend behind the 566 and repeat the process: 5660 / 622

Let's proceed to step 5:
When dividing 5660 by 622, we get 9 with a remainder of 62.
The next digit of our result is 9. 
Result so far: 139.0
If we take 5598 away from 5660, we end up with 62.
Include the next digit (3) from the dividend after 62, then repeat: 623 / 622

On to step 6:
The number 622 fits into 623 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1391.0
Deduct 622 from 623 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 622

Step 7:
622 goes into 17 0 times with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 13910.0
Subtracting 0 from 17 leaves us with 17.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 622

Going ahead to step 8:
The number 622 fits into 176 0 times, leaving a remainder of 176.
Use 0 as the next digit of our solution. 
Result so far: 139100.0
Subtracting 0 from 176 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 9:
If we divide 1760 by 622, we get 2 and a remainder of 516.
The next digit of our result is 2. 
Result so far: 139100.2
Deduct 1244 from 1760 and we're left with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Let's proceed to step 10:
When dividing 5160 by 622, we get 8 with a remainder of 184.
The next digit of our result is 8. 
Result so far: 139100.28
Deduct 4976 from 5160 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 11:
If we divide 1840 by 622, we get 2 and a remainder of 596.
The next digit of our result is 2. 
Result so far: 139100.282
The remainder is 596 after subtracting 1244 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Let's proceed to step 12:
When dividing 5960 by 622, we get 9 with a remainder of 362.
Put 9 as the next digit of the answer. 
Result so far: 139100.2829
Deduct 5598 from 5960 and we're left with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Moving on to step 13:
622 can be fit into 3620 5 times, resulting in a remainder of 510.
Put 5 as the next digit of the answer. 
Result so far: 139100.28295
If we take 3110 away from 3620, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Step 14:
If we divide 5100 by 622, we get 8 and a remainder of 124.
The next digit of our result is 8. 
Result so far: 139100.282958
If we take 4976 away from 5100, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 15:
1240 divided by 622 is 1 with a remainder of 618.
Put 1 as the next digit of the answer. 
Result so far: 139100.2829581
If we subtract 622 from 1240, we get 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Advancing to step 16:
6180 divided by 622 is 9 with a remainder of 582.
Record the quotient 9 as the next digit in the result. 
Result so far: 139100.28295819
Subtract 5598 from 6180 to get 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

After the division, we end up with 139100.28295819 and a remainder of 5.82e-07.
