Let's divide 70970404 by 210
We're looking to find how many times 210 goes into 70970404.

Let's proceed to step 1:
When dividing 7 by 210, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 210

On to step 2:
210 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Grab the next digit (9) from the dividend, add it to 70, then carry on: 709 / 210

Let's proceed to step 3:
The number 210 fits into 709 3 times, leaving a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 630 from 709 leaves us with 79.
Take the next digit (7) from the dividend and append it to 79, then repeat: 797 / 210

Moving on to step 4:
When dividing 797 by 210, we get 3 with a remainder of 167.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtract 630 from 797 to get 167.
Take the next digit (0) from the dividend and append it to 167, then repeat: 1670 / 210

On to step 5:
210 can be fit into 1670 7 times, resulting in a remainder of 200.
Put 7 as the next digit of the answer. 
Result so far: 337.0
If we take 1470 away from 1670, we end up with 200.
Include the next digit (4) from the dividend after 200, then repeat: 2004 / 210

Let's proceed to step 6:
2004 divided by 210 is 9 with a remainder of 114.
Record the quotient 9 as the next digit in the result. 
Result so far: 3379.0
Subtract 1890 from 2004 to get 114.
Bring next digit (0) of the dividend behind the 114 and repeat the process: 1140 / 210

Step 7:
210 can be fit into 1140 5 times, resulting in a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 33795.0
If we take 1050 away from 1140, we end up with 90.
Append the next digit (4) from the dividend to 90 and continue with: 904 / 210

Advancing to step 8:
210 can be fit into 904 4 times, resulting in a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 337954.0
If we subtract 840 from 904, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 9:
The number 210 fits into 640 3 times, leaving a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 337954.3
Deduct 630 from 640 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.

Moving on to step 10:
210 goes into 100 0 times with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 337954.3
Subtracting 0 from 100 leaves us 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 11:
210 goes into 1000 4 times with a remainder of 160.
Record the quotient 4 as the next digit in the result. 
Result so far: 337954.304
Subtracting 840 from 1000 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 12:
The number 210 fits into 1600 7 times, leaving a remainder of 130.
The next digit of our result is 7. 
Result so far: 337954.3047
Subtract 1470 from 1600 to get 130.
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 13:
The number 210 fits into 1300 6 times, leaving a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 337954.30476
Subtracting 1260 from 1300 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.

Step 14:
400 divided by 210 is 1 with a remainder of 190.
Write down 1 as next digit of the result. 
Result so far: 337954.304761
If we take 210 away from 400, we end up with 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 15:
The number 210 fits into 1900 9 times, leaving a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 337954.3047619
Subtracting 1890 from 1900 leaves us 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 16:
If we divide 100 by 210, we get 0 and a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 337954.3047619
Subtracting 0 from 100 leaves us 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.

After the division, we end up with 337954.3047619 and a remainder of 1e-07.
