8726489 divided by 851 
The aim is to understand the frequency of 851 in 8726489.

Going ahead to step 1:
851 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 851

Step 2:
851 can be fit into 87 0 times, resulting in a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Take the next digit (2) from the dividend and append it to 87, then repeat: 872 / 851

Moving on to step 3:
The number 851 fits into 872 1 times, leaving a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 21 after subtracting 851 from 872.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 851

Step 4:
If we divide 216 by 851, we get 0 and a remainder of 216.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 216 and we're left with 216.
Bring next digit (4) of the dividend behind the 216 and repeat the process: 2164 / 851

Advancing to step 5:
If we divide 2164 by 851, we get 2 and a remainder of 462.
Put 2 as the next digit of the answer. 
Result so far: 102.0
If we take 1702 away from 2164, we end up with 462.
Bring next digit (8) of the dividend behind the 462 and repeat the process: 4628 / 851

Going ahead to step 6:
If we divide 4628 by 851, we get 5 and a remainder of 373.
Write down 5 as next digit of the result. 
Result so far: 1025.0
If we subtract 4255 from 4628, we get 373.
Append the next digit (9) from the dividend to 373 and continue with: 3739 / 851

Moving on to step 7:
851 goes into 3739 4 times with a remainder of 335.
The next digit of our result is 4. 
Result so far: 10254.0
If we take 3404 away from 3739, we end up with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Step 8:
851 can be fit into 3350 3 times, resulting in a remainder of 797.
The number 3 becomes the next digit in our result. 
Result so far: 10254.3
Deduct 2553 from 3350 and we're left with 797.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7970, and continue the process.

Going ahead to step 9:
851 can be fit into 7970 9 times, resulting in a remainder of 311.
Record the quotient 9 as the next digit in the result. 
Result so far: 10254.39
Deduct 7659 from 7970 and we're left with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Step 10:
851 can be fit into 3110 3 times, resulting in a remainder of 557.
Use 3 as the next digit of our solution. 
Result so far: 10254.393
If we take 2553 away from 3110, we end up with 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Advancing to step 11:
The number 851 fits into 5570 6 times, leaving a remainder of 464.
Use 6 as the next digit of our solution. 
Result so far: 10254.3936
The remainder is 464 after subtracting 5106 from 5570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 12:
If we divide 4640 by 851, we get 5 and a remainder of 385.
Put 5 as the next digit of the answer. 
Result so far: 10254.39365
If we take 4255 away from 4640, we end up with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Going ahead to step 13:
If we divide 3850 by 851, we get 4 and a remainder of 446.
Use 4 as the next digit of our solution. 
Result so far: 10254.393654
If we subtract 3404 from 3850, we get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Going ahead to step 14:
The number 851 fits into 4460 5 times, leaving a remainder of 205.
The number 5 becomes the next digit in our result. 
Result so far: 10254.3936545
If we subtract 4255 from 4460, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 15:
851 can be fit into 2050 2 times, resulting in a remainder of 348.
Record the quotient 2 as the next digit in the result. 
Result so far: 10254.39365452
The remainder is 348 after subtracting 1702 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Our division results in 10254.39365452 with a remaining 3.48e-07.
