51978004 ÷ 819 
We want to figure out the number of times 51978004 can be divided by 819.

Moving on to step 1:
If we divide 5 by 819, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 819

On to step 2:
The number 819 fits into 51 0 times, leaving a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 819

Moving on to step 3:
The number 819 fits into 519 0 times, leaving a remainder of 519.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 519 after subtracting 0 from 519.
Append the next digit (7) from the dividend to 519 and continue with: 5197 / 819

Going ahead to step 4:
819 can be fit into 5197 6 times, resulting in a remainder of 283.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 4914 from 5197 to get 283.
Append the next digit (8) from the dividend to 283 and continue with: 2838 / 819

Going ahead to step 5:
If we divide 2838 by 819, we get 3 and a remainder of 381.
Use 3 as the next digit of our solution. 
Result so far: 63.0
The remainder is 381 after subtracting 2457 from 2838.
Grab the next digit (0) from the dividend, add it to 381, then carry on: 3810 / 819

Let's proceed to step 6:
3810 divided by 819 is 4 with a remainder of 534.
Use 4 as the next digit of our solution. 
Result so far: 634.0
Subtract 3276 from 3810 to get 534.
Fetch the next digit (0) from the dividend, attach it to 534 and continue: 5340 / 819

Let's proceed to step 7:
When dividing 5340 by 819, we get 6 with a remainder of 426.
Write down 6 as next digit of the result. 
Result so far: 6346.0
Deduct 4914 from 5340 and we're left with 426.
Take the next digit (4) from the dividend and append it to 426, then repeat: 4264 / 819

Going ahead to step 8:
The number 819 fits into 4264 5 times, leaving a remainder of 169.
The number 5 becomes the next digit in our result. 
Result so far: 63465.0
Subtract 4095 from 4264 to get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Let's proceed to step 9:
819 goes into 1690 2 times with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 63465.2
If we take 1638 away from 1690, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
520 divided by 819 is 0 with a remainder of 520.
Record the quotient 0 as the next digit in the result. 
Result so far: 63465.2
Subtract 0 from 520 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 11:
If we divide 5200 by 819, we get 6 and a remainder of 286.
Put 6 as the next digit of the answer. 
Result so far: 63465.206
If we take 4914 away from 5200, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 12:
When dividing 2860 by 819, we get 3 with a remainder of 403.
Put 3 as the next digit of the answer. 
Result so far: 63465.2063
Deduct 2457 from 2860 and we're left with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Step 13:
4030 divided by 819 is 4 with a remainder of 754.
Write down 4 as next digit of the result. 
Result so far: 63465.20634
The remainder is 754 after subtracting 3276 from 4030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Going ahead to step 14:
7540 divided by 819 is 9 with a remainder of 169.
Put 9 as the next digit of the answer. 
Result so far: 63465.206349
Subtracting 7371 from 7540 leaves us with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Advancing to step 15:
The number 819 fits into 1690 2 times, leaving a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 63465.2063492
If we subtract 1638 from 1690, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 16:
819 can be fit into 520 0 times, resulting in a remainder of 520.
Use 0 as the next digit of our solution. 
Result so far: 63465.2063492
Deduct 0 from 520 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

The quotient of the division is 63465.2063492, and the remainder is 5.2e-07.
