We divide 89813890 by 651
The aim is to understand the frequency of 651 in 89813890.

Let's proceed to step 1:
The number 651 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 651

On to step 2:
89 divided by 651 is 0 with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Take the next digit (8) from the dividend and append it to 89, then repeat: 898 / 651

Step 3:
When dividing 898 by 651, we get 1 with a remainder of 247.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 651 from 898 to get 247.
Grab the next digit (1) from the dividend, add it to 247, then carry on: 2471 / 651

On to step 4:
2471 divided by 651 is 3 with a remainder of 518.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 1953 from 2471 and we're left with 518.
Bring next digit (3) of the dividend behind the 518 and repeat the process: 5183 / 651

On to step 5:
651 goes into 5183 7 times with a remainder of 626.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
Deduct 4557 from 5183 and we're left with 626.
Take the next digit (8) from the dividend and append it to 626, then repeat: 6268 / 651

Step 6:
The number 651 fits into 6268 9 times, leaving a remainder of 409.
Write down 9 as next digit of the result. 
Result so far: 1379.0
If we take 5859 away from 6268, we end up with 409.
Append the next digit (9) from the dividend to 409 and continue with: 4099 / 651

Moving on to step 7:
If we divide 4099 by 651, we get 6 and a remainder of 193.
Record the quotient 6 as the next digit in the result. 
Result so far: 13796.0
The remainder is 193 after subtracting 3906 from 4099.
Include the next digit (0) from the dividend after 193, then repeat: 1930 / 651

On to step 8:
651 can be fit into 1930 2 times, resulting in a remainder of 628.
The next digit of our result is 2. 
Result so far: 137962.0
The remainder is 628 after subtracting 1302 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

On to step 9:
651 goes into 6280 9 times with a remainder of 421.
The next digit of our result is 9. 
Result so far: 137962.9
Subtracting 5859 from 6280 leaves us with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Moving on to step 10:
If we divide 4210 by 651, we get 6 and a remainder of 304.
The number 6 becomes the next digit in our result. 
Result so far: 137962.96
If we subtract 3906 from 4210, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 11:
651 can be fit into 3040 4 times, resulting in a remainder of 436.
The number 4 becomes the next digit in our result. 
Result so far: 137962.964
If we subtract 2604 from 3040, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

On to step 12:
If we divide 4360 by 651, we get 6 and a remainder of 454.
Write down 6 as next digit of the result. 
Result so far: 137962.9646
If we subtract 3906 from 4360, we get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Advancing to step 13:
651 can be fit into 4540 6 times, resulting in a remainder of 634.
Put 6 as the next digit of the answer. 
Result so far: 137962.96466
The remainder is 634 after subtracting 3906 from 4540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

After the division, we end up with 137962.96466 and a remainder of 0.000634.
