We're dividing 20860394 by 658 
We want to divide 20860394 by 658.

Advancing to step 1:
The number 658 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 658

Advancing to step 2:
20 divided by 658 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 658

Moving on to step 3:
When dividing 208 by 658, we get 0 with a remainder of 208.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 208, we get 208.
Take the next digit (6) from the dividend and append it to 208, then repeat: 2086 / 658

Advancing to step 4:
658 goes into 2086 3 times with a remainder of 112.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 1974 from 2086 leaves us with 112.
Append the next digit (0) from the dividend to 112 and continue with: 1120 / 658

Advancing to step 5:
When dividing 1120 by 658, we get 1 with a remainder of 462.
The next digit of our result is 1. 
Result so far: 31.0
Deduct 658 from 1120 and we're left with 462.
Fetch the next digit (3) from the dividend, attach it to 462 and continue: 4623 / 658

Moving on to step 6:
The number 658 fits into 4623 7 times, leaving a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 317.0
Subtract 4606 from 4623 to get 17.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 658

Going ahead to step 7:
The number 658 fits into 179 0 times, leaving a remainder of 179.
The number 0 becomes the next digit in our result. 
Result so far: 3170.0
The remainder is 179 after subtracting 0 from 179.
Fetch the next digit (4) from the dividend, attach it to 179 and continue: 1794 / 658

Step 8:
658 goes into 1794 2 times with a remainder of 478.
Use 2 as the next digit of our solution. 
Result so far: 31702.0
If we subtract 1316 from 1794, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Moving on to step 9:
The number 658 fits into 4780 7 times, leaving a remainder of 174.
Write down 7 as next digit of the result. 
Result so far: 31702.7
If we take 4606 away from 4780, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 10:
The number 658 fits into 1740 2 times, leaving a remainder of 424.
The number 2 becomes the next digit in our result. 
Result so far: 31702.72
Subtracting 1316 from 1740 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Let's proceed to step 11:
658 goes into 4240 6 times with a remainder of 292.
The next digit of our result is 6. 
Result so far: 31702.726
Subtract 3948 from 4240 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.

Let's proceed to step 12:
658 can be fit into 2920 4 times, resulting in a remainder of 288.
The number 4 becomes the next digit in our result. 
Result so far: 31702.7264
The remainder is 288 after subtracting 2632 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 13:
If we divide 2880 by 658, we get 4 and a remainder of 248.
Write down 4 as next digit of the result. 
Result so far: 31702.72644
Subtracting 2632 from 2880 leaves us 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.

In conclusion, the division gives 31702.72644 with a balance of 0.000248.
