45387590 ÷ 146 
The aim is to understand the frequency of 146 in 45387590.

On to step 1:
If we divide 4 by 146, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 146

Step 2:
45 divided by 146 is 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Grab the next digit (3) from the dividend, add it to 45, then carry on: 453 / 146

Advancing to step 3:
146 goes into 453 3 times with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 438 from 453, we get 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 146

Step 4:
The number 146 fits into 158 1 times, leaving a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we take 146 away from 158, we end up with 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 146

Moving on to step 5:
When dividing 127 by 146, we get 0 with a remainder of 127.
Write down 0 as next digit of the result. 
Result so far: 310.0
If we subtract 0 from 127, we get 127.
Bring next digit (5) of the dividend behind the 127 and repeat the process: 1275 / 146

Let's proceed to step 6:
When dividing 1275 by 146, we get 8 with a remainder of 107.
The next digit of our result is 8. 
Result so far: 3108.0
If we subtract 1168 from 1275, we get 107.
Append the next digit (9) from the dividend to 107 and continue with: 1079 / 146

Step 7:
When dividing 1079 by 146, we get 7 with a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 31087.0
Deduct 1022 from 1079 and we're left with 57.
Bring next digit (0) of the dividend behind the 57 and repeat the process: 570 / 146

Let's proceed to step 8:
The number 146 fits into 570 3 times, leaving a remainder of 132.
Write down 3 as next digit of the result. 
Result so far: 310873.0
If we take 438 away from 570, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 9:
146 can be fit into 1320 9 times, resulting in a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 310873.9
The remainder is 6 after subtracting 1314 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
146 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 310873.9
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
600 divided by 146 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 310873.904
If we take 584 away from 600, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
146 goes into 160 1 times with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 310873.9041
Subtract 146 from 160 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
146 can be fit into 140 0 times, resulting in a remainder of 140.
The next digit of our result is 0. 
Result so far: 310873.9041
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 14:
The number 146 fits into 1400 9 times, leaving a remainder of 86.
Write down 9 as next digit of the result. 
Result so far: 310873.904109
If we take 1314 away from 1400, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 15:
The number 146 fits into 860 5 times, leaving a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 310873.9041095
If we take 730 away from 860, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 16:
If we divide 1300 by 146, we get 8 and a remainder of 132.
The next digit of our result is 8. 
Result so far: 310873.90410958
Subtract 1168 from 1300 to 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.

The final result is 310873.90410958 with a remainder of 1.32e-07.
