57498968 divided by 210 
We want to figure out the number of times 57498968 can be divided by 210.

Going ahead to step 1:
When dividing 5 by 210, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 210

Step 2:
The number 210 fits into 57 0 times, leaving a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Grab the next digit (4) from the dividend, add it to 57, then carry on: 574 / 210

Advancing to step 3:
574 divided by 210 is 2 with a remainder of 154.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 154 after subtracting 420 from 574.
Take the next digit (9) from the dividend and append it to 154, then repeat: 1549 / 210

Step 4:
1549 divided by 210 is 7 with a remainder of 79.
Put 7 as the next digit of the answer. 
Result so far: 27.0
The remainder is 79 after subtracting 1470 from 1549.
Include the next digit (8) from the dividend after 79, then repeat: 798 / 210

On to step 5:
The number 210 fits into 798 3 times, leaving a remainder of 168.
Use 3 as the next digit of our solution. 
Result so far: 273.0
The remainder is 168 after subtracting 630 from 798.
Grab the next digit (9) from the dividend, add it to 168, then carry on: 1689 / 210

Moving on to step 6:
1689 divided by 210 is 8 with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 2738.0
If we take 1680 away from 1689, we end up with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 210

Step 7:
210 can be fit into 96 0 times, resulting in a remainder of 96.
The next digit of our result is 0. 
Result so far: 27380.0
If we take 0 away from 96, we end up with 96.
Append the next digit (8) from the dividend to 96 and continue with: 968 / 210

Let's proceed to step 8:
The number 210 fits into 968 4 times, leaving a remainder of 128.
Put 4 as the next digit of the answer. 
Result so far: 273804.0
Subtract 840 from 968 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 9:
1280 divided by 210 is 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 273804.6
Subtract 1260 from 1280 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
210 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 273804.6
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
2000 divided by 210 is 9 with a remainder of 110.
Write down 9 as next digit of the result. 
Result so far: 273804.609
Subtracting 1890 from 2000 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 12:
The number 210 fits into 1100 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 273804.6095
Subtracting 1050 from 1100 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
210 can be fit into 500 2 times, resulting in a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 273804.60952
If we take 420 away from 500, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 14:
210 can be fit into 800 3 times, resulting in a remainder of 170.
The number 3 becomes the next digit in our result. 
Result so far: 273804.609523
Deduct 630 from 800 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 15:
The number 210 fits into 1700 8 times, leaving a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 273804.6095238
Subtract 1680 from 1700 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 16:
If we divide 200 by 210, we get 0 and a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 273804.6095238
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 273804.6095238 and a remainder of 2e-07.
