We're dividing 73188715 by 535 
We want to figure out the number of times 73188715 can be divided by 535.

Going ahead to step 1:
When dividing 7 by 535, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 535

On to step 2:
When dividing 73 by 535, we get 0 with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Fetch the next digit (1) from the dividend, attach it to 73 and continue: 731 / 535

Step 3:
731 divided by 535 is 1 with a remainder of 196.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 535 from 731 to get 196.
Grab the next digit (8) from the dividend, add it to 196, then carry on: 1968 / 535

On to step 4:
If we divide 1968 by 535, we get 3 and a remainder of 363.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 1605 away from 1968, we end up with 363.
Take the next digit (8) from the dividend and append it to 363, then repeat: 3638 / 535

Step 5:
When dividing 3638 by 535, we get 6 with a remainder of 428.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
The remainder is 428 after subtracting 3210 from 3638.
Fetch the next digit (7) from the dividend, attach it to 428 and continue: 4287 / 535

On to step 6:
535 goes into 4287 8 times with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 1368.0
Deduct 4280 from 4287 and we're left with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 535

Step 7:
When dividing 71 by 535, we get 0 with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 13680.0
If we take 0 away from 71, we end up with 71.
Grab the next digit (5) from the dividend, add it to 71, then carry on: 715 / 535

On to step 8:
When dividing 715 by 535, we get 1 with a remainder of 180.
The number 1 becomes the next digit in our result. 
Result so far: 136801.0
Deduct 535 from 715 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 9:
If we divide 1800 by 535, we get 3 and a remainder of 195.
Put 3 as the next digit of the answer. 
Result so far: 136801.3
Subtracting 1605 from 1800 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 10:
1950 divided by 535 is 3 with a remainder of 345.
Put 3 as the next digit of the answer. 
Result so far: 136801.33
If we take 1605 away from 1950, we end up with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Our division results in 136801.33 with a remaining 0.345.
