73521260 ÷ 355 
We want to divide 73521260 by 355.

On to step 1:
When dividing 7 by 355, 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.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 355

Going ahead to step 2:
355 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 subtract 0 from 73, we get 73.
Append the next digit (5) from the dividend to 73 and continue with: 735 / 355

Advancing to step 3:
735 divided by 355 is 2 with a remainder of 25.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 710 from 735 and we're left with 25.
Append the next digit (2) from the dividend to 25 and continue with: 252 / 355

Let's proceed to step 4:
355 can be fit into 252 0 times, resulting in a remainder of 252.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 252, we get 252.
Append the next digit (1) from the dividend to 252 and continue with: 2521 / 355

On to step 5:
355 can be fit into 2521 7 times, resulting in a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 207.0
The remainder is 36 after subtracting 2485 from 2521.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 355

Moving on to step 6:
355 can be fit into 362 1 times, resulting in a remainder of 7.
The next digit of our result is 1. 
Result so far: 2071.0
Deduct 355 from 362 and we're left with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 355

Moving on to step 7:
76 divided by 355 is 0 with a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 20710.0
Subtracting 0 from 76 leaves us with 76.
Fetch the next digit (0) from the dividend, attach it to 76 and continue: 760 / 355

On to step 8:
When dividing 760 by 355, we get 2 with a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 207102.0
Subtracting 710 from 760 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
355 goes into 500 1 times with a remainder of 145.
The next digit of our result is 1. 
Result so far: 207102.1
Deduct 355 from 500 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 10:
355 goes into 1450 4 times with a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 207102.14
Subtract 1420 from 1450 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
The number 355 fits into 300 0 times, leaving a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 207102.14
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 12:
355 can be fit into 3000 8 times, resulting in a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 207102.1408
Deduct 2840 from 3000 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 13:
If we divide 1600 by 355, we get 4 and a remainder of 180.
The number 4 becomes the next digit in our result. 
Result so far: 207102.14084
Deduct 1420 from 1600 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.

Advancing to step 14:
The number 355 fits into 1800 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 207102.140845
Subtract 1775 from 1800 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 15:
The number 355 fits into 250 0 times, leaving a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 207102.140845
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 16:
When dividing 2500 by 355, we get 7 with a remainder of 15.
The next digit of our result is 7. 
Result so far: 207102.14084507
Subtracting 2485 from 2500 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 207102.14084507 and a remainder of 1.5e-08.
