We're dividing 98800521 by 951 
The aim is to understand the frequency of 951 in 98800521.

Moving on to step 1:
951 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 951

Advancing to step 2:
98 divided by 951 is 0 with a remainder of 98.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 98 leaves us with 98.
Bring next digit (8) of the dividend behind the 98 and repeat the process: 988 / 951

Let's proceed to step 3:
When dividing 988 by 951, we get 1 with a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 951 from 988 to get 37.
Take the next digit (0) from the dividend and append it to 37, then repeat: 370 / 951

Moving on to step 4:
If we divide 370 by 951, we get 0 and a remainder of 370.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 370, we get 370.
Include the next digit (0) from the dividend after 370, then repeat: 3700 / 951

Advancing to step 5:
When dividing 3700 by 951, we get 3 with a remainder of 847.
Put 3 as the next digit of the answer. 
Result so far: 103.0
Subtract 2853 from 3700 to get 847.
Grab the next digit (5) from the dividend, add it to 847, then carry on: 8475 / 951

On to step 6:
951 can be fit into 8475 8 times, resulting in a remainder of 867.
Use 8 as the next digit of our solution. 
Result so far: 1038.0
If we take 7608 away from 8475, we end up with 867.
Take the next digit (2) from the dividend and append it to 867, then repeat: 8672 / 951

Let's proceed to step 7:
When dividing 8672 by 951, we get 9 with a remainder of 113.
Record the quotient 9 as the next digit in the result. 
Result so far: 10389.0
Subtract 8559 from 8672 to get 113.
Fetch the next digit (1) from the dividend, attach it to 113 and continue: 1131 / 951

Moving on to step 8:
If we divide 1131 by 951, we get 1 and a remainder of 180.
Use 1 as the next digit of our solution. 
Result so far: 103891.0
If we take 951 away from 1131, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 9:
The number 951 fits into 1800 1 times, leaving a remainder of 849.
The next digit of our result is 1. 
Result so far: 103891.1
If we take 951 away from 1800, we end up with 849.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8490, and continue the process.

On to step 10:
If we divide 8490 by 951, we get 8 and a remainder of 882.
Record the quotient 8 as the next digit in the result. 
Result so far: 103891.18
If we subtract 7608 from 8490, we get 882.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8820, and continue the process.

Step 11:
The number 951 fits into 8820 9 times, leaving a remainder of 261.
Record the quotient 9 as the next digit in the result. 
Result so far: 103891.189
If we subtract 8559 from 8820, we get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Advancing to step 12:
The number 951 fits into 2610 2 times, leaving a remainder of 708.
The next digit of our result is 2. 
Result so far: 103891.1892
Subtract 1902 from 2610 to get 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Moving on to step 13:
When dividing 7080 by 951, we get 7 with a remainder of 423.
The number 7 becomes the next digit in our result. 
Result so far: 103891.18927
The remainder is 423 after subtracting 6657 from 7080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Advancing to step 14:
4230 divided by 951 is 4 with a remainder of 426.
Put 4 as the next digit of the answer. 
Result so far: 103891.189274
Subtract 3804 from 4230 to get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Let's proceed to step 15:
951 can be fit into 4260 4 times, resulting in a remainder of 456.
Record the quotient 4 as the next digit in the result. 
Result so far: 103891.1892744
If we subtract 3804 from 4260, we get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

The final outcome is 103891.1892744, with a leftover of 4.56e-06.
