We look at the division of 97356438 by 640 
Our goal is to divide 97356438 by 640.

On to step 1:
640 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 640

Going ahead to step 2:
97 divided by 640 is 0 with a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 97 to get 97.
Bring next digit (3) of the dividend behind the 97 and repeat the process: 973 / 640

Step 3:
If we divide 973 by 640, we get 1 and a remainder of 333.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 640 from 973 and we're left with 333.
Bring next digit (5) of the dividend behind the 333 and repeat the process: 3335 / 640

Let's proceed to step 4:
640 can be fit into 3335 5 times, resulting in a remainder of 135.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 3200 from 3335, we get 135.
Grab the next digit (6) from the dividend, add it to 135, then carry on: 1356 / 640

Step 5:
640 can be fit into 1356 2 times, resulting in a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 152.0
If we subtract 1280 from 1356, we get 76.
Grab the next digit (4) from the dividend, add it to 76, then carry on: 764 / 640

Let's proceed to step 6:
640 goes into 764 1 times with a remainder of 124.
The number 1 becomes the next digit in our result. 
Result so far: 1521.0
Subtract 640 from 764 to get 124.
Bring next digit (3) of the dividend behind the 124 and repeat the process: 1243 / 640

Going ahead to step 7:
The number 640 fits into 1243 1 times, leaving a remainder of 603.
Record the quotient 1 as the next digit in the result. 
Result so far: 15211.0
Subtract 640 from 1243 to get 603.
Take the next digit (8) from the dividend and append it to 603, then repeat: 6038 / 640

Moving on to step 8:
640 goes into 6038 9 times with a remainder of 278.
Put 9 as the next digit of the answer. 
Result so far: 152119.0
If we subtract 5760 from 6038, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

On to step 9:
640 can be fit into 2780 4 times, resulting in a remainder of 220.
Write down 4 as next digit of the result. 
Result so far: 152119.4
If we subtract 2560 from 2780, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 10:
The number 640 fits into 2200 3 times, leaving a remainder of 280.
Write down 3 as next digit of the result. 
Result so far: 152119.43
Deduct 1920 from 2200 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 11:
640 can be fit into 2800 4 times, resulting in a remainder of 240.
The number 4 becomes the next digit in our result. 
Result so far: 152119.434
Subtract 2560 from 2800 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.

On to step 12:
When dividing 2400 by 640, we get 3 with a remainder of 480.
Record the quotient 3 as the next digit in the result. 
Result so far: 152119.4343
The remainder is 480 after subtracting 1920 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 13:
640 goes into 4800 7 times with a remainder of 320.
The number 7 becomes the next digit in our result. 
Result so far: 152119.43437
The remainder is 320 after subtracting 4480 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 14:
640 can be fit into 3200 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 152119.434375
Subtract 3200 from 3200 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 15:
If we divide 0 by 640, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 152119.434375
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 16:
The number 640 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 152119.434375
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 152119.434375, and the remainder is 0.0.
