91172031 divided by 741 
The aim is to understand the frequency of 741 in 91172031.

On to step 1:
741 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 741

Going ahead to step 2:
When dividing 91 by 741, we get 0 with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Take the next digit (1) from the dividend and append it to 91, then repeat: 911 / 741

Advancing to step 3:
If we divide 911 by 741, we get 1 and a remainder of 170.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 741 from 911 leaves us with 170.
Fetch the next digit (7) from the dividend, attach it to 170 and continue: 1707 / 741

On to step 4:
When dividing 1707 by 741, we get 2 with a remainder of 225.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 1482 from 1707, we get 225.
Include the next digit (2) from the dividend after 225, then repeat: 2252 / 741

Advancing to step 5:
2252 divided by 741 is 3 with a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 123.0
Subtracting 2223 from 2252 leaves us with 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 741

Step 6:
If we divide 290 by 741, we get 0 and a remainder of 290.
Put 0 as the next digit of the answer. 
Result so far: 1230.0
If we subtract 0 from 290, we get 290.
Take the next digit (3) from the dividend and append it to 290, then repeat: 2903 / 741

Advancing to step 7:
741 goes into 2903 3 times with a remainder of 680.
Record the quotient 3 as the next digit in the result. 
Result so far: 12303.0
Deduct 2223 from 2903 and we're left with 680.
Append the next digit (1) from the dividend to 680 and continue with: 6801 / 741

Step 8:
When dividing 6801 by 741, we get 9 with a remainder of 132.
The next digit of our result is 9. 
Result so far: 123039.0
If we subtract 6669 from 6801, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 9:
When dividing 1320 by 741, we get 1 with a remainder of 579.
Record the quotient 1 as the next digit in the result. 
Result so far: 123039.1
If we subtract 741 from 1320, we get 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Moving on to step 10:
5790 divided by 741 is 7 with a remainder of 603.
The next digit of our result is 7. 
Result so far: 123039.17
If we subtract 5187 from 5790, we get 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Advancing to step 11:
741 can be fit into 6030 8 times, resulting in a remainder of 102.
The number 8 becomes the next digit in our result. 
Result so far: 123039.178
Subtracting 5928 from 6030 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 12:
1020 divided by 741 is 1 with a remainder of 279.
Put 1 as the next digit of the answer. 
Result so far: 123039.1781
If we take 741 away from 1020, we end up with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Step 13:
When dividing 2790 by 741, we get 3 with a remainder of 567.
Use 3 as the next digit of our solution. 
Result so far: 123039.17813
If we subtract 2223 from 2790, we get 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Step 14:
5670 divided by 741 is 7 with a remainder of 483.
Write down 7 as next digit of the result. 
Result so far: 123039.178137
Subtract 5187 from 5670 to get 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Going ahead to step 15:
741 goes into 4830 6 times with a remainder of 384.
Write down 6 as next digit of the result. 
Result so far: 123039.1781376
The remainder is 384 after subtracting 4446 from 4830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 16:
The number 741 fits into 3840 5 times, leaving a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 123039.17813765
Subtracting 3705 from 3840 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.

The final outcome is 123039.17813765, with a leftover of 1.35e-07.
