We look at the division of 83356186 by 640 
We want to divide 83356186 by 640.

Advancing to step 1:
8 divided by 640 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 640

Step 2:
640 can be fit into 83 0 times, resulting in a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Bring next digit (3) of the dividend behind the 83 and repeat the process: 833 / 640

Step 3:
640 goes into 833 1 times with a remainder of 193.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 640 from 833 to get 193.
Bring next digit (5) of the dividend behind the 193 and repeat the process: 1935 / 640

Advancing to step 4:
640 goes into 1935 3 times with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 15 after subtracting 1920 from 1935.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 640

Moving on to step 5:
The number 640 fits into 156 0 times, leaving a remainder of 156.
The number 0 becomes the next digit in our result. 
Result so far: 130.0
Subtracting 0 from 156 leaves us with 156.
Grab the next digit (1) from the dividend, add it to 156, then carry on: 1561 / 640

Step 6:
When dividing 1561 by 640, we get 2 with a remainder of 281.
Record the quotient 2 as the next digit in the result. 
Result so far: 1302.0
If we subtract 1280 from 1561, we get 281.
Grab the next digit (8) from the dividend, add it to 281, then carry on: 2818 / 640

Step 7:
2818 divided by 640 is 4 with a remainder of 258.
The next digit of our result is 4. 
Result so far: 13024.0
Deduct 2560 from 2818 and we're left with 258.
Take the next digit (6) from the dividend and append it to 258, then repeat: 2586 / 640

Step 8:
When dividing 2586 by 640, we get 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 130244.0
The remainder is 26 after subtracting 2560 from 2586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
260 divided by 640 is 0 with a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 130244.0
Subtracting 0 from 260 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 10:
When dividing 2600 by 640, we get 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 130244.04
The remainder is 40 after subtracting 2560 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
If we divide 400 by 640, we get 0 and a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 130244.04
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 12:
640 can be fit into 4000 6 times, resulting in a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 130244.0406
Subtracting 3840 from 4000 leaves us 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.

Moving on to step 13:
When dividing 1600 by 640, we get 2 with a remainder of 320.
The number 2 becomes the next digit in our result. 
Result so far: 130244.04062
Deduct 1280 from 1600 and we're left with 320.
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.
The number 5 becomes the next digit in our result. 
Result so far: 130244.040625
If we take 3200 away from 3200, 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.

Moving on to step 15:
640 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 130244.040625
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.

Let's proceed to step 16:
640 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 130244.040625
Deduct 0 from 0 and we're left 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.

In conclusion, the division gives 130244.040625 with a balance of 0.0.
