We're dividing 73986548 by 536 
The aim is to understand the frequency of 536 in 73986548.

Let's proceed to step 1:
The number 536 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 536

On to step 2:
536 goes into 73 0 times with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Include the next digit (9) from the dividend after 73, then repeat: 739 / 536

Advancing to step 3:
The number 536 fits into 739 1 times, leaving a remainder of 203.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 536 from 739 to get 203.
Append the next digit (8) from the dividend to 203 and continue with: 2038 / 536

Let's proceed to step 4:
The number 536 fits into 2038 3 times, leaving a remainder of 430.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 1608 from 2038 and we're left with 430.
Fetch the next digit (6) from the dividend, attach it to 430 and continue: 4306 / 536

Moving on to step 5:
536 goes into 4306 8 times with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
Subtract 4288 from 4306 to get 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 536

On to step 6:
536 goes into 185 0 times with a remainder of 185.
Use 0 as the next digit of our solution. 
Result so far: 1380.0
If we subtract 0 from 185, we get 185.
Append the next digit (4) from the dividend to 185 and continue with: 1854 / 536

Going ahead to step 7:
The number 536 fits into 1854 3 times, leaving a remainder of 246.
Use 3 as the next digit of our solution. 
Result so far: 13803.0
The remainder is 246 after subtracting 1608 from 1854.
Bring next digit (8) of the dividend behind the 246 and repeat the process: 2468 / 536

On to step 8:
When dividing 2468 by 536, we get 4 with a remainder of 324.
Put 4 as the next digit of the answer. 
Result so far: 138034.0
Deduct 2144 from 2468 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Moving on to step 9:
If we divide 3240 by 536, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 138034.6
If we take 3216 away from 3240, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
If we divide 240 by 536, we get 0 and a remainder of 240.
The next digit of our result is 0. 
Result so far: 138034.6
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 11:
If we divide 2400 by 536, we get 4 and a remainder of 256.
Put 4 as the next digit of the answer. 
Result so far: 138034.604
The remainder is 256 after subtracting 2144 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 12:
536 goes into 2560 4 times with a remainder of 416.
Write down 4 as next digit of the result. 
Result so far: 138034.6044
Deduct 2144 from 2560 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

The final outcome is 138034.6044, with a leftover of 0.00416.
