7536449 ÷ 637 
The aim is to understand the frequency of 637 in 7536449.

Going ahead to step 1:
637 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 637

Advancing to step 2:
637 can be fit into 75 0 times, resulting in a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Take the next digit (3) from the dividend and append it to 75, then repeat: 753 / 637

Let's proceed to step 3:
637 can be fit into 753 1 times, resulting in a remainder of 116.
The next digit of our result is 1. 
Result so far: 1.0
If we take 637 away from 753, we end up with 116.
Fetch the next digit (6) from the dividend, attach it to 116 and continue: 1166 / 637

Let's proceed to step 4:
1166 divided by 637 is 1 with a remainder of 529.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 637 from 1166 leaves us with 529.
Take the next digit (4) from the dividend and append it to 529, then repeat: 5294 / 637

Step 5:
5294 divided by 637 is 8 with a remainder of 198.
Write down 8 as next digit of the result. 
Result so far: 118.0
Subtract 5096 from 5294 to get 198.
Bring next digit (4) of the dividend behind the 198 and repeat the process: 1984 / 637

Step 6:
637 goes into 1984 3 times with a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 1183.0
The remainder is 73 after subtracting 1911 from 1984.
Include the next digit (9) from the dividend after 73, then repeat: 739 / 637

Advancing to step 7:
The number 637 fits into 739 1 times, leaving a remainder of 102.
The next digit of our result is 1. 
Result so far: 11831.0
If we take 637 away from 739, we end up 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.

Advancing to step 8:
If we divide 1020 by 637, we get 1 and a remainder of 383.
Use 1 as the next digit of our solution. 
Result so far: 11831.1
Deduct 637 from 1020 and we're left with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Step 9:
3830 divided by 637 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 11831.16
If we take 3822 away from 3830, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
637 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 11831.16
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
When dividing 800 by 637, we get 1 with a remainder of 163.
The number 1 becomes the next digit in our result. 
Result so far: 11831.1601
The remainder is 163 after subtracting 637 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

On to step 12:
637 can be fit into 1630 2 times, resulting in a remainder of 356.
Record the quotient 2 as the next digit in the result. 
Result so far: 11831.16012
Subtract 1274 from 1630 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 13:
637 goes into 3560 5 times with a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 11831.160125
Subtract 3185 from 3560 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 14:
637 can be fit into 3750 5 times, resulting in a remainder of 565.
Put 5 as the next digit of the answer. 
Result so far: 11831.1601255
Subtract 3185 from 3750 to get 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

After the division, we end up with 11831.1601255 and a remainder of 5.65e-06.
