71672620 ÷ 820 
The aim is to understand the frequency of 820 in 71672620.

On to step 1:
820 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 820

Going ahead to step 2:
71 divided by 820 is 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Append the next digit (6) from the dividend to 71 and continue with: 716 / 820

Step 3:
820 can be fit into 716 0 times, resulting in a remainder of 716.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 716 and we're left with 716.
Grab the next digit (7) from the dividend, add it to 716, then carry on: 7167 / 820

Going ahead to step 4:
If we divide 7167 by 820, we get 8 and a remainder of 607.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 6560 from 7167 leaves us with 607.
Take the next digit (2) from the dividend and append it to 607, then repeat: 6072 / 820

Advancing to step 5:
820 can be fit into 6072 7 times, resulting in a remainder of 332.
Write down 7 as next digit of the result. 
Result so far: 87.0
If we take 5740 away from 6072, we end up with 332.
Take the next digit (6) from the dividend and append it to 332, then repeat: 3326 / 820

Moving on to step 6:
820 goes into 3326 4 times with a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 874.0
If we take 3280 away from 3326, we end up with 46.
Bring next digit (2) of the dividend behind the 46 and repeat the process: 462 / 820

Moving on to step 7:
820 goes into 462 0 times with a remainder of 462.
Use 0 as the next digit of our solution. 
Result so far: 8740.0
Subtract 0 from 462 to get 462.
Append the next digit (0) from the dividend to 462 and continue with: 4620 / 820

Moving on to step 8:
820 goes into 4620 5 times with a remainder of 520.
Put 5 as the next digit of the answer. 
Result so far: 87405.0
If we subtract 4100 from 4620, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 9:
5200 divided by 820 is 6 with a remainder of 280.
Record the quotient 6 as the next digit in the result. 
Result so far: 87405.6
If we subtract 4920 from 5200, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 10:
2800 divided by 820 is 3 with a remainder of 340.
Record the quotient 3 as the next digit in the result. 
Result so far: 87405.63
Subtracting 2460 from 2800 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 11:
If we divide 3400 by 820, we get 4 and a remainder of 120.
The number 4 becomes the next digit in our result. 
Result so far: 87405.634
If we take 3280 away from 3400, we end up 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.

Advancing to step 12:
820 can be fit into 1200 1 times, resulting in a remainder of 380.
Record the quotient 1 as the next digit in the result. 
Result so far: 87405.6341
If we take 820 away from 1200, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 13:
820 goes into 3800 4 times with a remainder of 520.
The number 4 becomes the next digit in our result. 
Result so far: 87405.63414
If we subtract 3280 from 3800, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 14:
When dividing 5200 by 820, we get 6 with a remainder of 280.
Use 6 as the next digit of our solution. 
Result so far: 87405.634146
The remainder is 280 after subtracting 4920 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 15:
820 goes into 2800 3 times with a remainder of 340.
Use 3 as the next digit of our solution. 
Result so far: 87405.6341463
Deduct 2460 from 2800 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 16:
820 goes into 3400 4 times with a remainder of 120.
The number 4 becomes the next digit in our result. 
Result so far: 87405.63414634
If we take 3280 away from 3400, we end up 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.

The quotient of the division is 87405.63414634, and the remainder is 1.2e-07.
