83247148 ÷ 641 
We're looking to find how many times 641 goes into 83247148.

Moving on to step 1:
If we divide 8 by 641, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 641

Moving on to step 2:
If we divide 83 by 641, we get 0 and a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Include the next digit (2) from the dividend after 83, then repeat: 832 / 641

Step 3:
832 divided by 641 is 1 with a remainder of 191.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 641 from 832 leaves us with 191.
Take the next digit (4) from the dividend and append it to 191, then repeat: 1914 / 641

Moving on to step 4:
The number 641 fits into 1914 2 times, leaving a remainder of 632.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 632 after subtracting 1282 from 1914.
Append the next digit (7) from the dividend to 632 and continue with: 6327 / 641

Let's proceed to step 5:
The number 641 fits into 6327 9 times, leaving a remainder of 558.
Use 9 as the next digit of our solution. 
Result so far: 129.0
The remainder is 558 after subtracting 5769 from 6327.
Fetch the next digit (1) from the dividend, attach it to 558 and continue: 5581 / 641

Let's proceed to step 6:
If we divide 5581 by 641, we get 8 and a remainder of 453.
Use 8 as the next digit of our solution. 
Result so far: 1298.0
The remainder is 453 after subtracting 5128 from 5581.
Fetch the next digit (4) from the dividend, attach it to 453 and continue: 4534 / 641

Moving on to step 7:
4534 divided by 641 is 7 with a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 12987.0
Deduct 4487 from 4534 and we're left with 47.
Grab the next digit (8) from the dividend, add it to 47, then carry on: 478 / 641

Step 8:
641 can be fit into 478 0 times, resulting in a remainder of 478.
The next digit of our result is 0. 
Result so far: 129870.0
If we take 0 away from 478, we end up with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

On to step 9:
When dividing 4780 by 641, we get 7 with a remainder of 293.
Write down 7 as next digit of the result. 
Result so far: 129870.7
Deduct 4487 from 4780 and we're left with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Moving on to step 10:
When dividing 2930 by 641, we get 4 with a remainder of 366.
The next digit of our result is 4. 
Result so far: 129870.74
Subtract 2564 from 2930 to get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Moving on to step 11:
641 can be fit into 3660 5 times, resulting in a remainder of 455.
Put 5 as the next digit of the answer. 
Result so far: 129870.745
The remainder is 455 after subtracting 3205 from 3660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Advancing to step 12:
If we divide 4550 by 641, we get 7 and a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 129870.7457
If we subtract 4487 from 4550, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 13:
The number 641 fits into 630 0 times, leaving a remainder of 630.
The next digit of our result is 0. 
Result so far: 129870.7457
Subtract 0 from 630 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Going ahead to step 14:
If we divide 6300 by 641, we get 9 and a remainder of 531.
Write down 9 as next digit of the result. 
Result so far: 129870.745709
If we subtract 5769 from 6300, we get 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Moving on to step 15:
When dividing 5310 by 641, we get 8 with a remainder of 182.
Write down 8 as next digit of the result. 
Result so far: 129870.7457098
Subtract 5128 from 5310 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 16:
641 goes into 1820 2 times with a remainder of 538.
Put 2 as the next digit of the answer. 
Result so far: 129870.74570982
Subtract 1282 from 1820 to get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

The final result is 129870.74570982 with a remainder of 5.38e-07.
