We divide 51770639 by 641
Let's see how many times 641 fits into 51770639.

On to step 1:
The number 641 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 641

Let's proceed to step 2:
51 divided by 641 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Bring next digit (7) of the dividend behind the 51 and repeat the process: 517 / 641

Moving on to step 3:
517 divided by 641 is 0 with a remainder of 517.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 517 to get 517.
Take the next digit (7) from the dividend and append it to 517, then repeat: 5177 / 641

Moving on to step 4:
The number 641 fits into 5177 8 times, leaving a remainder of 49.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 5128 from 5177 and we're left with 49.
Grab the next digit (0) from the dividend, add it to 49, then carry on: 490 / 641

Step 5:
If we divide 490 by 641, we get 0 and a remainder of 490.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Subtracting 0 from 490 leaves us with 490.
Bring next digit (6) of the dividend behind the 490 and repeat the process: 4906 / 641

Step 6:
The number 641 fits into 4906 7 times, leaving a remainder of 419.
The number 7 becomes the next digit in our result. 
Result so far: 807.0
Subtract 4487 from 4906 to get 419.
Take the next digit (3) from the dividend and append it to 419, then repeat: 4193 / 641

Let's proceed to step 7:
The number 641 fits into 4193 6 times, leaving a remainder of 347.
Use 6 as the next digit of our solution. 
Result so far: 8076.0
The remainder is 347 after subtracting 3846 from 4193.
Fetch the next digit (9) from the dividend, attach it to 347 and continue: 3479 / 641

Let's proceed to step 8:
When dividing 3479 by 641, we get 5 with a remainder of 274.
Record the quotient 5 as the next digit in the result. 
Result so far: 80765.0
If we subtract 3205 from 3479, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 9:
The number 641 fits into 2740 4 times, leaving a remainder of 176.
Write down 4 as next digit of the result. 
Result so far: 80765.4
Deduct 2564 from 2740 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 10:
641 can be fit into 1760 2 times, resulting in a remainder of 478.
Use 2 as the next digit of our solution. 
Result so far: 80765.42
Subtracting 1282 from 1760 leaves us 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.

Advancing to step 11:
641 can be fit into 4780 7 times, resulting in a remainder of 293.
Put 7 as the next digit of the answer. 
Result so far: 80765.427
If we take 4487 away from 4780, we end up 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.

Step 12:
If we divide 2930 by 641, we get 4 and a remainder of 366.
Write down 4 as next digit of the result. 
Result so far: 80765.4274
Deduct 2564 from 2930 and we're left with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

On to step 13:
When dividing 3660 by 641, we get 5 with a remainder of 455.
The number 5 becomes the next digit in our result. 
Result so far: 80765.42745
Deduct 3205 from 3660 and we're left with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Going ahead to step 14:
If we divide 4550 by 641, we get 7 and a remainder of 63.
The next digit of our result is 7. 
Result so far: 80765.427457
If we take 4487 away from 4550, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 15:
641 can be fit into 630 0 times, resulting in a remainder of 630.
Put 0 as the next digit of the answer. 
Result so far: 80765.427457
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.

Moving on to step 16:
When dividing 6300 by 641, we get 9 with a remainder of 531.
The number 9 becomes the next digit in our result. 
Result so far: 80765.42745709
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.

The final outcome is 80765.42745709, with a leftover of 5.31e-07.
