Let's divide 19635739 by 210
We want to divide 19635739 by 210.

Advancing to step 1:
210 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 210

Going ahead to step 2:
19 divided by 210 is 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 210

Advancing to step 3:
196 divided by 210 is 0 with a remainder of 196.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 196 leaves us with 196.
Grab the next digit (3) from the dividend, add it to 196, then carry on: 1963 / 210

On to step 4:
The number 210 fits into 1963 9 times, leaving a remainder of 73.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 1890 from 1963, we get 73.
Take the next digit (5) from the dividend and append it to 73, then repeat: 735 / 210

Let's proceed to step 5:
210 can be fit into 735 3 times, resulting in a remainder of 105.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
If we take 630 away from 735, we end up with 105.
Take the next digit (7) from the dividend and append it to 105, then repeat: 1057 / 210

Advancing to step 6:
When dividing 1057 by 210, we get 5 with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 935.0
Subtract 1050 from 1057 to get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 210

Going ahead to step 7:
If we divide 73 by 210, we get 0 and a remainder of 73.
The next digit of our result is 0. 
Result so far: 9350.0
If we take 0 away from 73, we end up with 73.
Append the next digit (9) from the dividend to 73 and continue with: 739 / 210

Moving on to step 8:
If we divide 739 by 210, we get 3 and a remainder of 109.
Record the quotient 3 as the next digit in the result. 
Result so far: 93503.0
Subtracting 630 from 739 leaves us with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Advancing to step 9:
If we divide 1090 by 210, we get 5 and a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 93503.5
Subtracting 1050 from 1090 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
When dividing 400 by 210, we get 1 with a remainder of 190.
Put 1 as the next digit of the answer. 
Result so far: 93503.51
If we subtract 210 from 400, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 11:
210 can be fit into 1900 9 times, resulting in a remainder of 10.
The next digit of our result is 9. 
Result so far: 93503.519
Deduct 1890 from 1900 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
If we divide 100 by 210, we get 0 and a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 93503.519
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 13:
210 goes into 1000 4 times with a remainder of 160.
Put 4 as the next digit of the answer. 
Result so far: 93503.51904
The remainder is 160 after subtracting 840 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 14:
If we divide 1600 by 210, we get 7 and a remainder of 130.
The number 7 becomes the next digit in our result. 
Result so far: 93503.519047
The remainder is 130 after subtracting 1470 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 15:
1300 divided by 210 is 6 with a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 93503.5190476
Subtract 1260 from 1300 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 16:
If we divide 400 by 210, we get 1 and a remainder of 190.
The number 1 becomes the next digit in our result. 
Result so far: 93503.51904761
The remainder is 190 after subtracting 210 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

The final result is 93503.51904761 with a remainder of 1.9e-07.
