91537860 ÷ 651 
The aim is to understand the frequency of 651 in 91537860.

Advancing to step 1:
651 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 651

Going ahead to step 2:
651 goes into 91 0 times with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Bring next digit (5) of the dividend behind the 91 and repeat the process: 915 / 651

On to step 3:
651 can be fit into 915 1 times, resulting in a remainder of 264.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 651 from 915 to get 264.
Append the next digit (3) from the dividend to 264 and continue with: 2643 / 651

Going ahead to step 4:
If we divide 2643 by 651, we get 4 and a remainder of 39.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtract 2604 from 2643 to get 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 651

Let's proceed to step 5:
The number 651 fits into 397 0 times, leaving a remainder of 397.
Write down 0 as next digit of the result. 
Result so far: 140.0
If we subtract 0 from 397, we get 397.
Include the next digit (8) from the dividend after 397, then repeat: 3978 / 651

Let's proceed to step 6:
The number 651 fits into 3978 6 times, leaving a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 1406.0
Deduct 3906 from 3978 and we're left with 72.
Take the next digit (6) from the dividend and append it to 72, then repeat: 726 / 651

Advancing to step 7:
When dividing 726 by 651, we get 1 with a remainder of 75.
Record the quotient 1 as the next digit in the result. 
Result so far: 14061.0
Subtracting 651 from 726 leaves us with 75.
Take the next digit (0) from the dividend and append it to 75, then repeat: 750 / 651

Moving on to step 8:
651 can be fit into 750 1 times, resulting in a remainder of 99.
Record the quotient 1 as the next digit in the result. 
Result so far: 140611.0
If we subtract 651 from 750, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 9:
651 goes into 990 1 times with a remainder of 339.
Use 1 as the next digit of our solution. 
Result so far: 140611.1
If we take 651 away from 990, we end up with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

On to step 10:
When dividing 3390 by 651, we get 5 with a remainder of 135.
Record the quotient 5 as the next digit in the result. 
Result so far: 140611.15
Subtracting 3255 from 3390 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 11:
1350 divided by 651 is 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 140611.152
The remainder is 48 after subtracting 1302 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
If we divide 480 by 651, we get 0 and a remainder of 480.
Record the quotient 0 as the next digit in the result. 
Result so far: 140611.152
Subtracting 0 from 480 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 13:
If we divide 4800 by 651, we get 7 and a remainder of 243.
Use 7 as the next digit of our solution. 
Result so far: 140611.15207
The remainder is 243 after subtracting 4557 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Advancing to step 14:
651 goes into 2430 3 times with a remainder of 477.
Record the quotient 3 as the next digit in the result. 
Result so far: 140611.152073
If we subtract 1953 from 2430, we get 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Let's proceed to step 15:
651 goes into 4770 7 times with a remainder of 213.
Put 7 as the next digit of the answer. 
Result so far: 140611.1520737
Subtracting 4557 from 4770 leaves us with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Moving on to step 16:
The number 651 fits into 2130 3 times, leaving a remainder of 177.
Record the quotient 3 as the next digit in the result. 
Result so far: 140611.15207373
If we take 1953 away from 2130, we end up with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

In conclusion, the division gives 140611.15207373 with a balance of 1.77e-07.
