We look at the division of 23889426 by 210 
Our goal is to divide 23889426 by 210.

Advancing to step 1:
When dividing 2 by 210, we get 0 with 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 (3) from the dividend after 2, then repeat: 23 / 210

Moving on to step 2:
When dividing 23 by 210, we get 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 210

Advancing to step 3:
210 can be fit into 238 1 times, resulting in a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 28 after subtracting 210 from 238.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 210

Advancing to step 4:
210 can be fit into 288 1 times, resulting in a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 210 from 288, we get 78.
Take the next digit (9) from the dividend and append it to 78, then repeat: 789 / 210

Advancing to step 5:
The number 210 fits into 789 3 times, leaving a remainder of 159.
Write down 3 as next digit of the result. 
Result so far: 113.0
Subtracting 630 from 789 leaves us with 159.
Grab the next digit (4) from the dividend, add it to 159, then carry on: 1594 / 210

Step 6:
The number 210 fits into 1594 7 times, leaving a remainder of 124.
Use 7 as the next digit of our solution. 
Result so far: 1137.0
Subtracting 1470 from 1594 leaves us with 124.
Take the next digit (2) from the dividend and append it to 124, then repeat: 1242 / 210

Step 7:
If we divide 1242 by 210, we get 5 and a remainder of 192.
Record the quotient 5 as the next digit in the result. 
Result so far: 11375.0
If we take 1050 away from 1242, we end up with 192.
Include the next digit (6) from the dividend after 192, then repeat: 1926 / 210

On to step 8:
210 goes into 1926 9 times with a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 113759.0
If we take 1890 away from 1926, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
210 can be fit into 360 1 times, resulting in a remainder of 150.
Put 1 as the next digit of the answer. 
Result so far: 113759.1
Subtract 210 from 360 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 10:
If we divide 1500 by 210, we get 7 and a remainder of 30.
The number 7 becomes the next digit in our result. 
Result so far: 113759.17
If we subtract 1470 from 1500, 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.

Step 11:
The number 210 fits into 300 1 times, leaving a remainder of 90.
Record the quotient 1 as the next digit in the result. 
Result so far: 113759.171
If we take 210 away from 300, we end up 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 12:
210 goes into 900 4 times with a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 113759.1714
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 13:
The number 210 fits into 600 2 times, leaving a remainder of 180.
The number 2 becomes the next digit in our result. 
Result so far: 113759.17142
The remainder is 180 after subtracting 420 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 14:
210 goes into 1800 8 times with a remainder of 120.
Put 8 as the next digit of the answer. 
Result so far: 113759.171428
Deduct 1680 from 1800 and we're left 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.

Advancing to step 15:
When dividing 1200 by 210, we get 5 with a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 113759.1714285
If we subtract 1050 from 1200, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 16:
If we divide 1500 by 210, we get 7 and a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 113759.17142857
If we take 1470 away from 1500, we end up 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.

The quotient of the division is 113759.17142857, and the remainder is 3e-08.
