84533488 divided by 643 
Our goal is to divide 84533488 by 643.

On to step 1:
643 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 643

Moving on to step 2:
When dividing 84 by 643, we get 0 with a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Include the next digit (5) from the dividend after 84, then repeat: 845 / 643

Moving on to step 3:
643 goes into 845 1 times with a remainder of 202.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 643 from 845 leaves us with 202.
Grab the next digit (3) from the dividend, add it to 202, then carry on: 2023 / 643

Step 4:
643 goes into 2023 3 times with a remainder of 94.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 94 after subtracting 1929 from 2023.
Append the next digit (3) from the dividend to 94 and continue with: 943 / 643

On to step 5:
The number 643 fits into 943 1 times, leaving a remainder of 300.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
If we take 643 away from 943, we end up with 300.
Fetch the next digit (4) from the dividend, attach it to 300 and continue: 3004 / 643

Advancing to step 6:
643 goes into 3004 4 times with a remainder of 432.
Record the quotient 4 as the next digit in the result. 
Result so far: 1314.0
If we subtract 2572 from 3004, we get 432.
Bring next digit (8) of the dividend behind the 432 and repeat the process: 4328 / 643

Moving on to step 7:
When dividing 4328 by 643, we get 6 with a remainder of 470.
The number 6 becomes the next digit in our result. 
Result so far: 13146.0
If we subtract 3858 from 4328, we get 470.
Fetch the next digit (8) from the dividend, attach it to 470 and continue: 4708 / 643

Moving on to step 8:
When dividing 4708 by 643, we get 7 with a remainder of 207.
Put 7 as the next digit of the answer. 
Result so far: 131467.0
Subtract 4501 from 4708 to get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Going ahead to step 9:
The number 643 fits into 2070 3 times, leaving a remainder of 141.
Use 3 as the next digit of our solution. 
Result so far: 131467.3
Subtracting 1929 from 2070 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Let's proceed to step 10:
The number 643 fits into 1410 2 times, leaving a remainder of 124.
The next digit of our result is 2. 
Result so far: 131467.32
If we subtract 1286 from 1410, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 11:
If we divide 1240 by 643, we get 1 and a remainder of 597.
Record the quotient 1 as the next digit in the result. 
Result so far: 131467.321
The remainder is 597 after subtracting 643 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Going ahead to step 12:
5970 divided by 643 is 9 with a remainder of 183.
Record the quotient 9 as the next digit in the result. 
Result so far: 131467.3219
If we take 5787 away from 5970, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 13:
643 goes into 1830 2 times with a remainder of 544.
The next digit of our result is 2. 
Result so far: 131467.32192
Subtract 1286 from 1830 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Let's proceed to step 14:
643 goes into 5440 8 times with a remainder of 296.
The number 8 becomes the next digit in our result. 
Result so far: 131467.321928
Subtract 5144 from 5440 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 15:
When dividing 2960 by 643, we get 4 with a remainder of 388.
The next digit of our result is 4. 
Result so far: 131467.3219284
If we take 2572 away from 2960, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Going ahead to step 16:
3880 divided by 643 is 6 with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 131467.32192846
If we subtract 3858 from 3880, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 131467.32192846 with a remainder of 2.2e-08.
