93091209 divided by 210 
Our goal is to divide 93091209 by 210.

Let's proceed to step 1:
210 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 210

Advancing to step 2:
210 can be fit into 93 0 times, resulting in a remainder of 93.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 93 to get 93.
Fetch the next digit (0) from the dividend, attach it to 93 and continue: 930 / 210

Advancing to step 3:
210 can be fit into 930 4 times, resulting in a remainder of 90.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 90 after subtracting 840 from 930.
Grab the next digit (9) from the dividend, add it to 90, then carry on: 909 / 210

Step 4:
210 can be fit into 909 4 times, resulting in a remainder of 69.
Put 4 as the next digit of the answer. 
Result so far: 44.0
If we subtract 840 from 909, we get 69.
Take the next digit (1) from the dividend and append it to 69, then repeat: 691 / 210

Moving on to step 5:
The number 210 fits into 691 3 times, leaving a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 443.0
The remainder is 61 after subtracting 630 from 691.
Include the next digit (2) from the dividend after 61, then repeat: 612 / 210

Going ahead to step 6:
If we divide 612 by 210, we get 2 and a remainder of 192.
Write down 2 as next digit of the result. 
Result so far: 4432.0
Deduct 420 from 612 and we're left with 192.
Take the next digit (0) from the dividend and append it to 192, then repeat: 1920 / 210

Advancing to step 7:
The number 210 fits into 1920 9 times, leaving a remainder of 30.
The next digit of our result is 9. 
Result so far: 44329.0
If we subtract 1890 from 1920, we get 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 210

On to step 8:
309 divided by 210 is 1 with a remainder of 99.
Put 1 as the next digit of the answer. 
Result so far: 443291.0
Subtract 210 from 309 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 9:
When dividing 990 by 210, we get 4 with a remainder of 150.
Put 4 as the next digit of the answer. 
Result so far: 443291.4
The remainder is 150 after subtracting 840 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 10:
When dividing 1500 by 210, we get 7 with a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 443291.47
The remainder is 30 after subtracting 1470 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
210 goes into 300 1 times with a remainder of 90.
Use 1 as the next digit of our solution. 
Result so far: 443291.471
Deduct 210 from 300 and we're left 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.

Going ahead to step 12:
When dividing 900 by 210, we get 4 with a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 443291.4714
Subtracting 840 from 900 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
The number 210 fits into 600 2 times, leaving a remainder of 180.
Put 2 as the next digit of the answer. 
Result so far: 443291.47142
Subtracting 420 from 600 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 14:
1800 divided by 210 is 8 with a remainder of 120.
Put 8 as the next digit of the answer. 
Result so far: 443291.471428
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.

Step 15:
210 can be fit into 1200 5 times, resulting in a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 443291.4714285
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 16:
210 goes into 1500 7 times with a remainder of 30.
The number 7 becomes the next digit in our result. 
Result so far: 443291.47142857
The remainder is 30 after subtracting 1470 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 443291.47142857 with a remaining 3e-08.
