Let's divide 91948641 by 145
The aim is to understand the frequency of 145 in 91948641.

Advancing to step 1:
If we divide 9 by 145, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 145

On to step 2:
145 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.
Append the next digit (9) from the dividend to 91 and continue with: 919 / 145

Advancing to step 3:
When dividing 919 by 145, we get 6 with a remainder of 49.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 870 from 919 leaves us with 49.
Bring next digit (4) of the dividend behind the 49 and repeat the process: 494 / 145

Step 4:
494 divided by 145 is 3 with a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 63.0
Subtract 435 from 494 to get 59.
Append the next digit (8) from the dividend to 59 and continue with: 598 / 145

Let's proceed to step 5:
145 goes into 598 4 times with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 634.0
If we take 580 away from 598, we end up with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 145

Step 6:
The number 145 fits into 186 1 times, leaving a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 6341.0
Deduct 145 from 186 and we're left with 41.
Include the next digit (4) from the dividend after 41, then repeat: 414 / 145

Going ahead to step 7:
The number 145 fits into 414 2 times, leaving a remainder of 124.
Write down 2 as next digit of the result. 
Result so far: 63412.0
If we take 290 away from 414, we end up with 124.
Bring next digit (1) of the dividend behind the 124 and repeat the process: 1241 / 145

Advancing to step 8:
The number 145 fits into 1241 8 times, leaving a remainder of 81.
Use 8 as the next digit of our solution. 
Result so far: 634128.0
Deduct 1160 from 1241 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 9:
145 goes into 810 5 times with a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 634128.5
Subtract 725 from 810 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 10:
850 divided by 145 is 5 with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 634128.55
Subtracting 725 from 850 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

The final outcome is 634128.55, with a leftover of 0.125.
