Let's divide 51847493 by 686
We want to divide 51847493 by 686.

Moving on to step 1:
When dividing 5 by 686, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 686

Advancing to step 2:
51 divided by 686 is 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Take the next digit (8) from the dividend and append it to 51, then repeat: 518 / 686

Let's proceed to step 3:
686 can be fit into 518 0 times, resulting in a remainder of 518.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 518 after subtracting 0 from 518.
Append the next digit (4) from the dividend to 518 and continue with: 5184 / 686

Moving on to step 4:
686 can be fit into 5184 7 times, resulting in a remainder of 382.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 382 after subtracting 4802 from 5184.
Bring next digit (7) of the dividend behind the 382 and repeat the process: 3827 / 686

Advancing to step 5:
The number 686 fits into 3827 5 times, leaving a remainder of 397.
Use 5 as the next digit of our solution. 
Result so far: 75.0
Subtract 3430 from 3827 to get 397.
Grab the next digit (4) from the dividend, add it to 397, then carry on: 3974 / 686

Moving on to step 6:
The number 686 fits into 3974 5 times, leaving a remainder of 544.
Write down 5 as next digit of the result. 
Result so far: 755.0
Subtracting 3430 from 3974 leaves us with 544.
Grab the next digit (9) from the dividend, add it to 544, then carry on: 5449 / 686

Let's proceed to step 7:
If we divide 5449 by 686, we get 7 and a remainder of 647.
The number 7 becomes the next digit in our result. 
Result so far: 7557.0
If we subtract 4802 from 5449, we get 647.
Append the next digit (3) from the dividend to 647 and continue with: 6473 / 686

Going ahead to step 8:
The number 686 fits into 6473 9 times, leaving a remainder of 299.
The next digit of our result is 9. 
Result so far: 75579.0
If we subtract 6174 from 6473, we get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Advancing to step 9:
The number 686 fits into 2990 4 times, leaving a remainder of 246.
The number 4 becomes the next digit in our result. 
Result so far: 75579.4
Subtract 2744 from 2990 to get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

On to step 10:
2460 divided by 686 is 3 with a remainder of 402.
Put 3 as the next digit of the answer. 
Result so far: 75579.43
If we take 2058 away from 2460, we end up with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Going ahead to step 11:
If we divide 4020 by 686, we get 5 and a remainder of 590.
The next digit of our result is 5. 
Result so far: 75579.435
Subtract 3430 from 4020 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Going ahead to step 12:
686 can be fit into 5900 8 times, resulting in a remainder of 412.
Use 8 as the next digit of our solution. 
Result so far: 75579.4358
Subtracting 5488 from 5900 leaves us with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

On to step 13:
When dividing 4120 by 686, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 75579.43586
If we take 4116 away from 4120, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
40 divided by 686 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 75579.43586
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 15:
When dividing 400 by 686, we get 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 75579.43586
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

In conclusion, the division gives 75579.43586 with a balance of 4e-06.
