We're dividing 79523127 by 643 
Our goal is to divide 79523127 by 643.

Let's proceed to step 1:
643 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 643

On to step 2:
When dividing 79 by 643, we get 0 with a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Include the next digit (5) from the dividend after 79, then repeat: 795 / 643

On to step 3:
795 divided by 643 is 1 with a remainder of 152.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 643 from 795 and we're left with 152.
Include the next digit (2) from the dividend after 152, then repeat: 1522 / 643

On to step 4:
When dividing 1522 by 643, we get 2 with a remainder of 236.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 1286 from 1522 leaves us with 236.
Fetch the next digit (3) from the dividend, attach it to 236 and continue: 2363 / 643

On to step 5:
643 can be fit into 2363 3 times, resulting in a remainder of 434.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
The remainder is 434 after subtracting 1929 from 2363.
Bring next digit (1) of the dividend behind the 434 and repeat the process: 4341 / 643

Moving on to step 6:
If we divide 4341 by 643, we get 6 and a remainder of 483.
Write down 6 as next digit of the result. 
Result so far: 1236.0
If we take 3858 away from 4341, we end up with 483.
Bring next digit (2) of the dividend behind the 483 and repeat the process: 4832 / 643

Moving on to step 7:
4832 divided by 643 is 7 with a remainder of 331.
Use 7 as the next digit of our solution. 
Result so far: 12367.0
Subtract 4501 from 4832 to get 331.
Include the next digit (7) from the dividend after 331, then repeat: 3317 / 643

Advancing to step 8:
643 goes into 3317 5 times with a remainder of 102.
Put 5 as the next digit of the answer. 
Result so far: 123675.0
If we subtract 3215 from 3317, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 9:
643 can be fit into 1020 1 times, resulting in a remainder of 377.
Write down 1 as next digit of the result. 
Result so far: 123675.1
If we take 643 away from 1020, we end up with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

On to step 10:
643 goes into 3770 5 times with a remainder of 555.
Use 5 as the next digit of our solution. 
Result so far: 123675.15
Deduct 3215 from 3770 and we're left with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Advancing to step 11:
643 goes into 5550 8 times with a remainder of 406.
Write down 8 as next digit of the result. 
Result so far: 123675.158
Subtract 5144 from 5550 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Step 12:
643 can be fit into 4060 6 times, resulting in a remainder of 202.
Write down 6 as next digit of the result. 
Result so far: 123675.1586
If we take 3858 away from 4060, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 13:
643 goes into 2020 3 times with a remainder of 91.
The next digit of our result is 3. 
Result so far: 123675.15863
Deduct 1929 from 2020 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 14:
643 can be fit into 910 1 times, resulting in a remainder of 267.
Put 1 as the next digit of the answer. 
Result so far: 123675.158631
The remainder is 267 after subtracting 643 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

On to step 15:
643 goes into 2670 4 times with a remainder of 98.
Write down 4 as next digit of the result. 
Result so far: 123675.1586314
Subtract 2572 from 2670 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 16:
When dividing 980 by 643, we get 1 with a remainder of 337.
The number 1 becomes the next digit in our result. 
Result so far: 123675.15863141
Subtracting 643 from 980 leaves us with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

After the division, we end up with 123675.15863141 and a remainder of 3.37e-07.
