Step 2:
643 can be fit into 73 0 times, resulting in a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Take the next digit (0) from the dividend and append it to 73, then repeat: 730 / 643

On to step 3:
643 can be fit into 730 1 times, resulting in a remainder of 87.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 87 after subtracting 643 from 730.

Step 4:
643 can be fit into 879 1 times, resulting in a remainder of 236.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 236 after subtracting 643 from 879.
Include the next digit (4) from the dividend after 236, then repeat: 2364 / 643

Moving on to step 5:
643 can be fit into 2364 3 times, resulting in a remainder of 435.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
The remainder is 435 after subtracting 1929 from 2364.
Take the next digit (0) from the dividend and append it to 435, then repeat: 4350 / 643

Step 6:
The number 643 fits into 4350 6 times, leaving a remainder of 492.
Write down 6 as next digit of the result. 
Result so far: 1136.0
Subtracting 3858 from 4350 leaves us with 492.
Append the next digit (1) from the dividend to 492 and continue with: 4921 / 643

Advancing to step 7:
The number 643 fits into 4921 7 times, leaving a remainder of 420.
Put 7 as the next digit of the answer. 
Result so far: 11367.0
If we take 4501 away from 4921, we end up with 420.
Include the next digit (5) from the dividend after 420, then repeat: 4205 / 643

Advancing to step 8:
643 can be fit into 4205 6 times, resulting in a remainder of 347.
Record the quotient 6 as the next digit in the result. 
Result so far: 113676.0
Deduct 3858 from 4205 and we're left with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Let's proceed to step 9:
643 goes into 3470 5 times with a remainder of 255.
Record the quotient 5 as the next digit in the result. 
Result so far: 113676.5
Subtracting 3215 from 3470 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Let's proceed to step 10:
The number 643 fits into 2550 3 times, leaving a remainder of 621.
Put 3 as the next digit of the answer. 
Result so far: 113676.53
If we take 1929 away from 2550, we end up with 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

Let's proceed to step 11:
6210 divided by 643 is 9 with a remainder of 423.
The next digit of our result is 9. 
Result so far: 113676.539
Deduct 5787 from 6210 and we're left with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Let's proceed to step 12:
643 can be fit into 4230 6 times, resulting in a remainder of 372.
Use 6 as the next digit of our solution. 
Result so far: 113676.5396
Subtracting 3858 from 4230 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Step 13:
When dividing 3720 by 643, we get 5 with a remainder of 505.
Put 5 as the next digit of the answer. 
Result so far: 113676.53965
If we take 3215 away from 3720, we end up with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Going ahead to step 14:
The number 643 fits into 5050 7 times, leaving a remainder of 549.
Put 7 as the next digit of the answer. 
Result so far: 113676.539657
If we subtract 4501 from 5050, we get 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

On to step 15:
643 can be fit into 5490 8 times, resulting in a remainder of 346.
Write down 8 as next digit of the result. 
Result so far: 113676.5396578
Deduct 5144 from 5490 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Step 16:
The number 643 fits into 3460 5 times, leaving a remainder of 245.
Write down 5 as next digit of the result. 
Result so far: 113676.53965785
If we subtract 3215 from 3460, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

The final outcome is 113676.53965785, with a leftover of 2.45e-07.
