We're dividing 83153075 by 641 
We want to figure out the number of times 83153075 can be divided by 641.

Let's proceed to step 1:
641 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 641

Moving on to step 2:
If we divide 83 by 641, we get 0 and a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Append the next digit (1) from the dividend to 83 and continue with: 831 / 641

Step 3:
641 can be fit into 831 1 times, resulting in a remainder of 190.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 641 from 831 to get 190.
Bring next digit (5) of the dividend behind the 190 and repeat the process: 1905 / 641

On to step 4:
The number 641 fits into 1905 2 times, leaving a remainder of 623.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1282 from 1905 and we're left with 623.
Grab the next digit (3) from the dividend, add it to 623, then carry on: 6233 / 641

On to step 5:
641 can be fit into 6233 9 times, resulting in a remainder of 464.
Write down 9 as next digit of the result. 
Result so far: 129.0
Subtracting 5769 from 6233 leaves us with 464.
Bring next digit (0) of the dividend behind the 464 and repeat the process: 4640 / 641

Step 6:
If we divide 4640 by 641, we get 7 and a remainder of 153.
Put 7 as the next digit of the answer. 
Result so far: 1297.0
Deduct 4487 from 4640 and we're left with 153.
Fetch the next digit (7) from the dividend, attach it to 153 and continue: 1537 / 641

Step 7:
641 can be fit into 1537 2 times, resulting in a remainder of 255.
The next digit of our result is 2. 
Result so far: 12972.0
If we subtract 1282 from 1537, we get 255.
Include the next digit (5) from the dividend after 255, then repeat: 2555 / 641

Let's proceed to step 8:
2555 divided by 641 is 3 with a remainder of 632.
The number 3 becomes the next digit in our result. 
Result so far: 129723.0
The remainder is 632 after subtracting 1923 from 2555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Advancing to step 9:
6320 divided by 641 is 9 with a remainder of 551.
Put 9 as the next digit of the answer. 
Result so far: 129723.9
The remainder is 551 after subtracting 5769 from 6320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Advancing to step 10:
641 can be fit into 5510 8 times, resulting in a remainder of 382.
The next digit of our result is 8. 
Result so far: 129723.98
Deduct 5128 from 5510 and we're left with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Step 11:
641 can be fit into 3820 5 times, resulting in a remainder of 615.
Write down 5 as next digit of the result. 
Result so far: 129723.985
Subtract 3205 from 3820 to get 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Advancing to step 12:
If we divide 6150 by 641, we get 9 and a remainder of 381.
Use 9 as the next digit of our solution. 
Result so far: 129723.9859
If we take 5769 away from 6150, we end up with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

On to step 13:
3810 divided by 641 is 5 with a remainder of 605.
The next digit of our result is 5. 
Result so far: 129723.98595
The remainder is 605 after subtracting 3205 from 3810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Let's proceed to step 14:
641 goes into 6050 9 times with a remainder of 281.
The number 9 becomes the next digit in our result. 
Result so far: 129723.985959
The remainder is 281 after subtracting 5769 from 6050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

On to step 15:
The number 641 fits into 2810 4 times, leaving a remainder of 246.
The number 4 becomes the next digit in our result. 
Result so far: 129723.9859594
If we take 2564 away from 2810, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 16:
The number 641 fits into 2460 3 times, leaving a remainder of 537.
The number 3 becomes the next digit in our result. 
Result so far: 129723.98595943
If we subtract 1923 from 2460, we get 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

After the division, we end up with 129723.98595943 and a remainder of 5.37e-07.
