We divide 612789 by 86
We want to figure out the number of times 612789 can be divided by 86.

On to step 1:
6 divided by 86 is 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.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 86

Going ahead to step 2:
The number 86 fits into 61 0 times, leaving a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Append the next digit (2) from the dividend to 61 and continue with: 612 / 86

Let's proceed to step 3:
86 can be fit into 612 7 times, resulting in a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 10 after subtracting 602 from 612.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 86

Advancing to step 4:
The number 86 fits into 107 1 times, leaving a remainder of 21.
The next digit of our result is 1. 
Result so far: 71.0
If we take 86 away from 107, we end up with 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 86

Going ahead to step 5:
When dividing 218 by 86, we get 2 with a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 712.0
If we subtract 172 from 218, we get 46.
Grab the next digit (9) from the dividend, add it to 46, then carry on: 469 / 86

Step 6:
86 can be fit into 469 5 times, resulting in a remainder of 39.
Put 5 as the next digit of the answer. 
Result so far: 7125.0
If we take 430 away from 469, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
86 goes into 390 4 times with a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 7125.4
If we subtract 344 from 390, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 8:
460 divided by 86 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 7125.45
If we subtract 430 from 460, we 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.

On to step 9:
300 divided by 86 is 3 with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 7125.453
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
If we divide 420 by 86, we get 4 and a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 7125.4534
Subtract 344 from 420 to 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.

Step 11:
86 goes into 760 8 times with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 7125.45348
If we subtract 688 from 760, 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.

Let's proceed to step 12:
720 divided by 86 is 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 7125.453488
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.

After the division, we end up with 7125.453488 and a remainder of 3.2e-06.
