Let's divide 97312303 by 139
The aim is to understand the frequency of 139 in 97312303.

Advancing to step 1:
139 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
Deduct 0 from 9 and we're left with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 139

Going ahead to step 2:
When dividing 97 by 139, we get 0 with a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 97 to get 97.
Bring next digit (3) of the dividend behind the 97 and repeat the process: 973 / 139

Step 3:
When dividing 973 by 139, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 973 from 973 to get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 139

Advancing to step 4:
1 divided by 139 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 70.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 139

Going ahead to step 5:
139 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 700.0
If we take 0 away from 12, we end up with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 139

Advancing to step 6:
When dividing 123 by 139, we get 0 with a remainder of 123.
The next digit of our result is 0. 
Result so far: 7000.0
If we subtract 0 from 123, we get 123.
Take the next digit (0) from the dividend and append it to 123, then repeat: 1230 / 139

On to step 7:
If we divide 1230 by 139, we get 8 and a remainder of 118.
Write down 8 as next digit of the result. 
Result so far: 70008.0
Subtract 1112 from 1230 to get 118.
Bring next digit (3) of the dividend behind the 118 and repeat the process: 1183 / 139

Moving on to step 8:
When dividing 1183 by 139, we get 8 with a remainder of 71.
Use 8 as the next digit of our solution. 
Result so far: 700088.0
If we take 1112 away from 1183, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 9:
139 can be fit into 710 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 700088.5
If we subtract 695 from 710, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
The number 139 fits into 150 1 times, leaving a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 700088.51
If we take 139 away from 150, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
The number 139 fits into 110 0 times, leaving a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 700088.51
The remainder is 110 after subtracting 0 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 12:
When dividing 1100 by 139, we get 7 with a remainder of 127.
Record the quotient 7 as the next digit in the result. 
Result so far: 700088.5107
Subtract 973 from 1100 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Advancing to step 13:
If we divide 1270 by 139, we get 9 and a remainder of 19.
The next digit of our result is 9. 
Result so far: 700088.51079
If we take 1251 away from 1270, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 14:
When dividing 190 by 139, we get 1 with a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 700088.510791
If we take 139 away from 190, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 15:
510 divided by 139 is 3 with a remainder of 93.
Put 3 as the next digit of the answer. 
Result so far: 700088.5107913
The remainder is 93 after subtracting 417 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 16:
930 divided by 139 is 6 with a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 700088.51079136
If we take 834 away from 930, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The final outcome is 700088.51079136, with a leftover of 9.6e-08.
