We divide 15671264 by 210
Our goal is to divide 15671264 by 210.

Advancing to step 1:
1 divided by 210 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 210

Moving on to step 2:
15 divided by 210 is 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 210

Going ahead to step 3:
210 goes into 156 0 times with a remainder of 156.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 156, we get 156.
Grab the next digit (7) from the dividend, add it to 156, then carry on: 1567 / 210

Moving on to step 4:
If we divide 1567 by 210, we get 7 and a remainder of 97.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 1470 from 1567, we get 97.
Include the next digit (1) from the dividend after 97, then repeat: 971 / 210

Advancing to step 5:
210 goes into 971 4 times with a remainder of 131.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
Deduct 840 from 971 and we're left with 131.
Take the next digit (2) from the dividend and append it to 131, then repeat: 1312 / 210

Let's proceed to step 6:
The number 210 fits into 1312 6 times, leaving a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 746.0
If we subtract 1260 from 1312, we get 52.
Take the next digit (6) from the dividend and append it to 52, then repeat: 526 / 210

Going ahead to step 7:
526 divided by 210 is 2 with a remainder of 106.
Put 2 as the next digit of the answer. 
Result so far: 7462.0
Deduct 420 from 526 and we're left with 106.
Bring next digit (4) of the dividend behind the 106 and repeat the process: 1064 / 210

On to step 8:
If we divide 1064 by 210, we get 5 and a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 74625.0
Subtract 1050 from 1064 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
210 can be fit into 140 0 times, resulting in a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 74625.0
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 10:
When dividing 1400 by 210, we get 6 with a remainder of 140.
Use 6 as the next digit of our solution. 
Result so far: 74625.06
Deduct 1260 from 1400 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 11:
When dividing 1400 by 210, we get 6 with a remainder of 140.
Record the quotient 6 as the next digit in the result. 
Result so far: 74625.066
The remainder is 140 after subtracting 1260 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final result is 74625.066 with a remainder of 0.014.
