Let's divide 53474923 by 145
The aim is to understand the frequency of 145 in 53474923.

Going ahead to step 1:
5 divided by 145 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 145

Moving on to step 2:
145 can be fit into 53 0 times, resulting in a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Fetch the next digit (4) from the dividend, attach it to 53 and continue: 534 / 145

On to step 3:
534 divided by 145 is 3 with a remainder of 99.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 435 from 534 to get 99.
Take the next digit (7) from the dividend and append it to 99, then repeat: 997 / 145

Step 4:
When dividing 997 by 145, we get 6 with a remainder of 127.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Deduct 870 from 997 and we're left with 127.
Grab the next digit (4) from the dividend, add it to 127, then carry on: 1274 / 145

Step 5:
1274 divided by 145 is 8 with a remainder of 114.
Put 8 as the next digit of the answer. 
Result so far: 368.0
If we subtract 1160 from 1274, we get 114.
Grab the next digit (9) from the dividend, add it to 114, then carry on: 1149 / 145

Step 6:
If we divide 1149 by 145, we get 7 and a remainder of 134.
Put 7 as the next digit of the answer. 
Result so far: 3687.0
Subtracting 1015 from 1149 leaves us with 134.
Fetch the next digit (2) from the dividend, attach it to 134 and continue: 1342 / 145

Step 7:
145 can be fit into 1342 9 times, resulting in a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 36879.0
The remainder is 37 after subtracting 1305 from 1342.
Bring next digit (3) of the dividend behind the 37 and repeat the process: 373 / 145

Advancing to step 8:
When dividing 373 by 145, we get 2 with a remainder of 83.
Put 2 as the next digit of the answer. 
Result so far: 368792.0
If we take 290 away from 373, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 9:
830 divided by 145 is 5 with a remainder of 105.
Record the quotient 5 as the next digit in the result. 
Result so far: 368792.5
Deduct 725 from 830 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 10:
145 goes into 1050 7 times with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 368792.57
If we subtract 1015 from 1050, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 11:
The number 145 fits into 350 2 times, leaving a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 368792.572
Deduct 290 from 350 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
When dividing 600 by 145, we get 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 368792.5724
The remainder is 20 after subtracting 580 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
If we divide 200 by 145, we get 1 and a remainder of 55.
The number 1 becomes the next digit in our result. 
Result so far: 368792.57241
If we subtract 145 from 200, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 14:
If we divide 550 by 145, we get 3 and a remainder of 115.
The next digit of our result is 3. 
Result so far: 368792.572413
If we subtract 435 from 550, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 15:
145 can be fit into 1150 7 times, resulting in a remainder of 135.
The number 7 becomes the next digit in our result. 
Result so far: 368792.5724137
Deduct 1015 from 1150 and we're left 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.

Let's proceed to step 16:
1350 divided by 145 is 9 with a remainder of 45.
The number 9 becomes the next digit in our result. 
Result so far: 368792.57241379
The remainder is 45 after subtracting 1305 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Our division results in 368792.57241379 with a remaining 4.5e-08.
