Let's divide 85137990 by 448
The aim is to understand the frequency of 448 in 85137990.

Let's proceed to step 1:
If we divide 8 by 448, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 448

Let's proceed to step 2:
The number 448 fits into 85 0 times, leaving a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Bring next digit (1) of the dividend behind the 85 and repeat the process: 851 / 448

Step 3:
851 divided by 448 is 1 with a remainder of 403.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 448 away from 851, we end up with 403.
Include the next digit (3) from the dividend after 403, then repeat: 4033 / 448

Step 4:
The number 448 fits into 4033 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 4032 from 4033 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 448

On to step 5:
17 divided by 448 is 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 190.0
If we take 0 away from 17, we end up with 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 448

On to step 6:
448 goes into 179 0 times with a remainder of 179.
Use 0 as the next digit of our solution. 
Result so far: 1900.0
Subtracting 0 from 179 leaves us with 179.
Take the next digit (9) from the dividend and append it to 179, then repeat: 1799 / 448

Going ahead to step 7:
1799 divided by 448 is 4 with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 19004.0
Subtract 1792 from 1799 to get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 448

Going ahead to step 8:
70 divided by 448 is 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 190040.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
700 divided by 448 is 1 with a remainder of 252.
Write down 1 as next digit of the result. 
Result so far: 190040.1
Deduct 448 from 700 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 10:
448 goes into 2520 5 times with a remainder of 280.
The next digit of our result is 5. 
Result so far: 190040.15
If we subtract 2240 from 2520, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 11:
448 goes into 2800 6 times with a remainder of 112.
Write down 6 as next digit of the result. 
Result so far: 190040.156
If we take 2688 away from 2800, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 12:
When dividing 1120 by 448, we get 2 with a remainder of 224.
Record the quotient 2 as the next digit in the result. 
Result so far: 190040.1562
If we subtract 896 from 1120, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 13:
If we divide 2240 by 448, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 190040.15625
Subtract 2240 from 2240 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 14:
If we divide 0 by 448, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 190040.15625
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 15:
If we divide 0 by 448, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 190040.15625
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 190040.15625 and a remainder of 0.0.
