We look at the division of 54970749 by 749 
The aim is to understand the frequency of 749 in 54970749.

Moving on to step 1:
If we divide 5 by 749, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 749

Advancing to step 2:
749 can be fit into 54 0 times, resulting in a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Take the next digit (9) from the dividend and append it to 54, then repeat: 549 / 749

Advancing to step 3:
The number 749 fits into 549 0 times, leaving a remainder of 549.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 549 and we're left with 549.
Append the next digit (7) from the dividend to 549 and continue with: 5497 / 749

Step 4:
If we divide 5497 by 749, we get 7 and a remainder of 254.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 5243 from 5497, we get 254.
Fetch the next digit (0) from the dividend, attach it to 254 and continue: 2540 / 749

Advancing to step 5:
If we divide 2540 by 749, we get 3 and a remainder of 293.
Put 3 as the next digit of the answer. 
Result so far: 73.0
The remainder is 293 after subtracting 2247 from 2540.
Fetch the next digit (7) from the dividend, attach it to 293 and continue: 2937 / 749

Advancing to step 6:
When dividing 2937 by 749, we get 3 with a remainder of 690.
Put 3 as the next digit of the answer. 
Result so far: 733.0
Subtract 2247 from 2937 to get 690.
Fetch the next digit (4) from the dividend, attach it to 690 and continue: 6904 / 749

Step 7:
If we divide 6904 by 749, we get 9 and a remainder of 163.
Use 9 as the next digit of our solution. 
Result so far: 7339.0
Deduct 6741 from 6904 and we're left with 163.
Take the next digit (9) from the dividend and append it to 163, then repeat: 1639 / 749

Advancing to step 8:
749 can be fit into 1639 2 times, resulting in a remainder of 141.
Write down 2 as next digit of the result. 
Result so far: 73392.0
Subtracting 1498 from 1639 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 9:
If we divide 1410 by 749, we get 1 and a remainder of 661.
The next digit of our result is 1. 
Result so far: 73392.1
Deduct 749 from 1410 and we're left with 661.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6610, and continue the process.

Step 10:
The number 749 fits into 6610 8 times, leaving a remainder of 618.
The next digit of our result is 8. 
Result so far: 73392.18
Subtract 5992 from 6610 to get 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Advancing to step 11:
When dividing 6180 by 749, we get 8 with a remainder of 188.
The next digit of our result is 8. 
Result so far: 73392.188
The remainder is 188 after subtracting 5992 from 6180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

The final result is 73392.188 with a remainder of 0.0188.
