Let's divide 52124424 by 686
We want to figure out the number of times 52124424 can be divided by 686.

Advancing to step 1:
686 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 686

Moving on to step 2:
686 can be fit into 52 0 times, resulting in a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 686

Going ahead to step 3:
686 goes into 521 0 times with a remainder of 521.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 521 leaves us with 521.
Take the next digit (2) from the dividend and append it to 521, then repeat: 5212 / 686

Advancing to step 4:
If we divide 5212 by 686, we get 7 and a remainder of 410.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 4802 away from 5212, we end up with 410.
Fetch the next digit (4) from the dividend, attach it to 410 and continue: 4104 / 686

Moving on to step 5:
4104 divided by 686 is 5 with a remainder of 674.
Put 5 as the next digit of the answer. 
Result so far: 75.0
Subtract 3430 from 4104 to get 674.
Fetch the next digit (4) from the dividend, attach it to 674 and continue: 6744 / 686

Step 6:
If we divide 6744 by 686, we get 9 and a remainder of 570.
Record the quotient 9 as the next digit in the result. 
Result so far: 759.0
If we subtract 6174 from 6744, we get 570.
Fetch the next digit (2) from the dividend, attach it to 570 and continue: 5702 / 686

Step 7:
When dividing 5702 by 686, we get 8 with a remainder of 214.
The next digit of our result is 8. 
Result so far: 7598.0
Deduct 5488 from 5702 and we're left with 214.
Take the next digit (4) from the dividend and append it to 214, then repeat: 2144 / 686

Moving on to step 8:
If we divide 2144 by 686, we get 3 and a remainder of 86.
The number 3 becomes the next digit in our result. 
Result so far: 75983.0
If we subtract 2058 from 2144, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 9:
If we divide 860 by 686, we get 1 and a remainder of 174.
Record the quotient 1 as the next digit in the result. 
Result so far: 75983.1
The remainder is 174 after subtracting 686 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 10:
If we divide 1740 by 686, we get 2 and a remainder of 368.
Write down 2 as next digit of the result. 
Result so far: 75983.12
Subtracting 1372 from 1740 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 11:
The number 686 fits into 3680 5 times, leaving a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 75983.125
If we take 3430 away from 3680, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 12:
2500 divided by 686 is 3 with a remainder of 442.
Use 3 as the next digit of our solution. 
Result so far: 75983.1253
Subtracting 2058 from 2500 leaves us with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Moving on to step 13:
4420 divided by 686 is 6 with a remainder of 304.
The next digit of our result is 6. 
Result so far: 75983.12536
Deduct 4116 from 4420 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 14:
686 goes into 3040 4 times with a remainder of 296.
Put 4 as the next digit of the answer. 
Result so far: 75983.125364
If we subtract 2744 from 3040, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 15:
When dividing 2960 by 686, we get 4 with a remainder of 216.
Use 4 as the next digit of our solution. 
Result so far: 75983.1253644
If we take 2744 away from 2960, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

After the division, we end up with 75983.1253644 and a remainder of 2.16e-06.
