Let's divide 51637490 by 813
We want to figure out the number of times 51637490 can be divided by 813.

Let's proceed to step 1:
5 divided by 813 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 813

On to step 2:
The number 813 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Grab the next digit (6) from the dividend, add it to 51, then carry on: 516 / 813

Let's proceed to step 3:
813 goes into 516 0 times with a remainder of 516.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 516 after subtracting 0 from 516.
Grab the next digit (3) from the dividend, add it to 516, then carry on: 5163 / 813

Going ahead to step 4:
813 can be fit into 5163 6 times, resulting in a remainder of 285.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 4878 from 5163 and we're left with 285.
Grab the next digit (7) from the dividend, add it to 285, then carry on: 2857 / 813

Advancing to step 5:
2857 divided by 813 is 3 with a remainder of 418.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Subtracting 2439 from 2857 leaves us with 418.
Take the next digit (4) from the dividend and append it to 418, then repeat: 4184 / 813

Moving on to step 6:
813 can be fit into 4184 5 times, resulting in a remainder of 119.
The next digit of our result is 5. 
Result so far: 635.0
If we take 4065 away from 4184, we end up with 119.
Bring next digit (9) of the dividend behind the 119 and repeat the process: 1199 / 813

On to step 7:
When dividing 1199 by 813, we get 1 with a remainder of 386.
Put 1 as the next digit of the answer. 
Result so far: 6351.0
Subtract 813 from 1199 to get 386.
Bring next digit (0) of the dividend behind the 386 and repeat the process: 3860 / 813

On to step 8:
813 can be fit into 3860 4 times, resulting in a remainder of 608.
Put 4 as the next digit of the answer. 
Result so far: 63514.0
If we subtract 3252 from 3860, we get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

On to step 9:
If we divide 6080 by 813, we get 7 and a remainder of 389.
Record the quotient 7 as the next digit in the result. 
Result so far: 63514.7
Subtract 5691 from 6080 to get 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

On to step 10:
813 can be fit into 3890 4 times, resulting in a remainder of 638.
Write down 4 as next digit of the result. 
Result so far: 63514.74
If we take 3252 away from 3890, we end up with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Step 11:
813 can be fit into 6380 7 times, resulting in a remainder of 689.
Put 7 as the next digit of the answer. 
Result so far: 63514.747
The remainder is 689 after subtracting 5691 from 6380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

Advancing to step 12:
If we divide 6890 by 813, we get 8 and a remainder of 386.
The next digit of our result is 8. 
Result so far: 63514.7478
If we subtract 6504 from 6890, we get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Step 13:
813 can be fit into 3860 4 times, resulting in a remainder of 608.
The number 4 becomes the next digit in our result. 
Result so far: 63514.74784
If we subtract 3252 from 3860, we get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Advancing to step 14:
813 goes into 6080 7 times with a remainder of 389.
The next digit of our result is 7. 
Result so far: 63514.747847
Subtracting 5691 from 6080 leaves us with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

On to step 15:
The number 813 fits into 3890 4 times, leaving a remainder of 638.
The number 4 becomes the next digit in our result. 
Result so far: 63514.7478474
If we take 3252 away from 3890, we end up with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Advancing to step 16:
813 goes into 6380 7 times with a remainder of 689.
Write down 7 as next digit of the result. 
Result so far: 63514.74784747
Subtract 5691 from 6380 to get 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

The final result is 63514.74784747 with a remainder of 6.89e-07.
