2974031 divided by 643 
We're looking to find how many times 643 goes into 2974031.

Going ahead to step 1:
The number 643 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 643

Let's proceed to step 2:
643 can be fit into 29 0 times, resulting in a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 643

Let's proceed to step 3:
643 can be fit into 297 0 times, resulting in a remainder of 297.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 297 after subtracting 0 from 297.
Bring next digit (4) of the dividend behind the 297 and repeat the process: 2974 / 643

Advancing to step 4:
2974 divided by 643 is 4 with a remainder of 402.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 2572 away from 2974, we end up with 402.
Bring next digit (0) of the dividend behind the 402 and repeat the process: 4020 / 643

Moving on to step 5:
When dividing 4020 by 643, we get 6 with a remainder of 162.
The next digit of our result is 6. 
Result so far: 46.0
Subtract 3858 from 4020 to get 162.
Include the next digit (3) from the dividend after 162, then repeat: 1623 / 643

On to step 6:
If we divide 1623 by 643, we get 2 and a remainder of 337.
Use 2 as the next digit of our solution. 
Result so far: 462.0
Deduct 1286 from 1623 and we're left with 337.
Grab the next digit (1) from the dividend, add it to 337, then carry on: 3371 / 643

Going ahead to step 7:
When dividing 3371 by 643, we get 5 with a remainder of 156.
Record the quotient 5 as the next digit in the result. 
Result so far: 4625.0
If we take 3215 away from 3371, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 8:
The number 643 fits into 1560 2 times, leaving a remainder of 274.
Use 2 as the next digit of our solution. 
Result so far: 4625.2
Deduct 1286 from 1560 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 9:
The number 643 fits into 2740 4 times, leaving a remainder of 168.
Write down 4 as next digit of the result. 
Result so far: 4625.24
Subtract 2572 from 2740 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 10:
643 can be fit into 1680 2 times, resulting in a remainder of 394.
Use 2 as the next digit of our solution. 
Result so far: 4625.242
Subtracting 1286 from 1680 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Step 11:
When dividing 3940 by 643, we get 6 with a remainder of 82.
The next digit of our result is 6. 
Result so far: 4625.2426
If we subtract 3858 from 3940, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 12:
643 can be fit into 820 1 times, resulting in a remainder of 177.
The number 1 becomes the next digit in our result. 
Result so far: 4625.24261
Deduct 643 from 820 and we're left with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Let's proceed to step 13:
The number 643 fits into 1770 2 times, leaving a remainder of 484.
The next digit of our result is 2. 
Result so far: 4625.242612
If we take 1286 away from 1770, we end up with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Moving on to step 14:
When dividing 4840 by 643, we get 7 with a remainder of 339.
Use 7 as the next digit of our solution. 
Result so far: 4625.2426127
If we take 4501 away from 4840, we end up with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

On to step 15:
3390 divided by 643 is 5 with a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 4625.24261275
Deduct 3215 from 3390 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

The final outcome is 4625.24261275, with a leftover of 1.75e-07.
