We look at the division of 20603181 by 210 
We want to divide 20603181 by 210.

Advancing to step 1:
The number 210 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 210

Moving on to step 2:
The number 210 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 210

On to step 3:
210 goes into 206 0 times with a remainder of 206.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 206 after subtracting 0 from 206.
Grab the next digit (0) from the dividend, add it to 206, then carry on: 2060 / 210

Advancing to step 4:
The number 210 fits into 2060 9 times, leaving a remainder of 170.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 1890 from 2060 leaves us with 170.
Include the next digit (3) from the dividend after 170, then repeat: 1703 / 210

Moving on to step 5:
When dividing 1703 by 210, we get 8 with a remainder of 23.
Put 8 as the next digit of the answer. 
Result so far: 98.0
If we take 1680 away from 1703, we end up with 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 210

Advancing to step 6:
When dividing 231 by 210, we get 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 981.0
Subtracting 210 from 231 leaves us with 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 210

Moving on to step 7:
210 can be fit into 218 1 times, resulting in a remainder of 8.
The next digit of our result is 1. 
Result so far: 9811.0
Subtracting 210 from 218 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 210

Let's proceed to step 8:
210 can be fit into 81 0 times, resulting in a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 98110.0
If we subtract 0 from 81, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 9:
810 divided by 210 is 3 with a remainder of 180.
Put 3 as the next digit of the answer. 
Result so far: 98110.3
The remainder is 180 after subtracting 630 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 10:
The number 210 fits into 1800 8 times, leaving a remainder of 120.
Use 8 as the next digit of our solution. 
Result so far: 98110.38
If we take 1680 away from 1800, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 11:
When dividing 1200 by 210, we get 5 with a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 98110.385
Deduct 1050 from 1200 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 12:
1500 divided by 210 is 7 with a remainder of 30.
The number 7 becomes the next digit in our result. 
Result so far: 98110.3857
Deduct 1470 from 1500 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
210 can be fit into 300 1 times, resulting in a remainder of 90.
The next digit of our result is 1. 
Result so far: 98110.38571
Subtracting 210 from 300 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 14:
The number 210 fits into 900 4 times, leaving a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 98110.385714
The remainder is 60 after subtracting 840 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 15:
The number 210 fits into 600 2 times, leaving a remainder of 180.
Use 2 as the next digit of our solution. 
Result so far: 98110.3857142
If we subtract 420 from 600, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 16:
The number 210 fits into 1800 8 times, leaving a remainder of 120.
The next digit of our result is 8. 
Result so far: 98110.38571428
If we take 1680 away from 1800, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final result is 98110.38571428 with a remainder of 1.2e-07.
