Let's divide 86242517 by 668
Our goal is to divide 86242517 by 668.

Let's proceed to step 1:
668 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 668

Moving on to step 2:
86 divided by 668 is 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Append the next digit (2) from the dividend to 86 and continue with: 862 / 668

On to step 3:
862 divided by 668 is 1 with a remainder of 194.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 668 from 862, we get 194.
Bring next digit (4) of the dividend behind the 194 and repeat the process: 1944 / 668

Moving on to step 4:
When dividing 1944 by 668, we get 2 with a remainder of 608.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 1336 from 1944, we get 608.
Bring next digit (2) of the dividend behind the 608 and repeat the process: 6082 / 668

Moving on to step 5:
If we divide 6082 by 668, we get 9 and a remainder of 70.
Write down 9 as next digit of the result. 
Result so far: 129.0
If we subtract 6012 from 6082, we get 70.
Fetch the next digit (5) from the dividend, attach it to 70 and continue: 705 / 668

Moving on to step 6:
705 divided by 668 is 1 with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 1291.0
Subtract 668 from 705 to get 37.
Append the next digit (1) from the dividend to 37 and continue with: 371 / 668

Let's proceed to step 7:
The number 668 fits into 371 0 times, leaving a remainder of 371.
Use 0 as the next digit of our solution. 
Result so far: 12910.0
The remainder is 371 after subtracting 0 from 371.
Grab the next digit (7) from the dividend, add it to 371, then carry on: 3717 / 668

Moving on to step 8:
The number 668 fits into 3717 5 times, leaving a remainder of 377.
Write down 5 as next digit of the result. 
Result so far: 129105.0
Subtracting 3340 from 3717 leaves us with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Advancing to step 9:
668 can be fit into 3770 5 times, resulting in a remainder of 430.
The number 5 becomes the next digit in our result. 
Result so far: 129105.5
If we take 3340 away from 3770, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 10:
4300 divided by 668 is 6 with a remainder of 292.
Write down 6 as next digit of the result. 
Result so far: 129105.56
Subtract 4008 from 4300 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 11:
668 can be fit into 2920 4 times, resulting in a remainder of 248.
The number 4 becomes the next digit in our result. 
Result so far: 129105.564
If we take 2672 away from 2920, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 12:
When dividing 2480 by 668, we get 3 with a remainder of 476.
The next digit of our result is 3. 
Result so far: 129105.5643
If we take 2004 away from 2480, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 13:
668 goes into 4760 7 times with a remainder of 84.
The number 7 becomes the next digit in our result. 
Result so far: 129105.56437
If we take 4676 away from 4760, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 14:
840 divided by 668 is 1 with a remainder of 172.
Record the quotient 1 as the next digit in the result. 
Result so far: 129105.564371
Subtract 668 from 840 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 15:
When dividing 1720 by 668, we get 2 with a remainder of 384.
Write down 2 as next digit of the result. 
Result so far: 129105.5643712
If we take 1336 away from 1720, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 16:
When dividing 3840 by 668, we get 5 with a remainder of 500.
The next digit of our result is 5. 
Result so far: 129105.56437125
If we take 3340 away from 3840, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

In conclusion, the division gives 129105.56437125 with a balance of 5e-07.
