42974019 divided by 686 
Let's see how many times 686 fits into 42974019.

Let's proceed to step 1:
When dividing 4 by 686, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 686

Advancing to step 2:
If we divide 42 by 686, we get 0 and a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Fetch the next digit (9) from the dividend, attach it to 42 and continue: 429 / 686

Advancing to step 3:
686 goes into 429 0 times with a remainder of 429.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 429 after subtracting 0 from 429.
Fetch the next digit (7) from the dividend, attach it to 429 and continue: 4297 / 686

Step 4:
If we divide 4297 by 686, we get 6 and a remainder of 181.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 4116 from 4297, we get 181.
Append the next digit (4) from the dividend to 181 and continue with: 1814 / 686

Let's proceed to step 5:
If we divide 1814 by 686, we get 2 and a remainder of 442.
Put 2 as the next digit of the answer. 
Result so far: 62.0
If we subtract 1372 from 1814, we get 442.
Bring next digit (0) of the dividend behind the 442 and repeat the process: 4420 / 686

Step 6:
4420 divided by 686 is 6 with a remainder of 304.
Use 6 as the next digit of our solution. 
Result so far: 626.0
If we subtract 4116 from 4420, we get 304.
Grab the next digit (1) from the dividend, add it to 304, then carry on: 3041 / 686

Let's proceed to step 7:
If we divide 3041 by 686, we get 4 and a remainder of 297.
Record the quotient 4 as the next digit in the result. 
Result so far: 6264.0
If we subtract 2744 from 3041, we get 297.
Include the next digit (9) from the dividend after 297, then repeat: 2979 / 686

Let's proceed to step 8:
686 can be fit into 2979 4 times, resulting in a remainder of 235.
Record the quotient 4 as the next digit in the result. 
Result so far: 62644.0
If we take 2744 away from 2979, we end up with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 9:
686 can be fit into 2350 3 times, resulting in a remainder of 292.
The next digit of our result is 3. 
Result so far: 62644.3
The remainder is 292 after subtracting 2058 from 2350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 10:
If we divide 2920 by 686, we get 4 and a remainder of 176.
The number 4 becomes the next digit in our result. 
Result so far: 62644.34
If we subtract 2744 from 2920, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 11:
686 goes into 1760 2 times with a remainder of 388.
Write down 2 as next digit of the result. 
Result so far: 62644.342
Subtracting 1372 from 1760 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 12:
686 can be fit into 3880 5 times, resulting in a remainder of 450.
The number 5 becomes the next digit in our result. 
Result so far: 62644.3425
Subtract 3430 from 3880 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 13:
If we divide 4500 by 686, we get 6 and a remainder of 384.
Put 6 as the next digit of the answer. 
Result so far: 62644.34256
Subtracting 4116 from 4500 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 14:
When dividing 3840 by 686, we get 5 with a remainder of 410.
The number 5 becomes the next digit in our result. 
Result so far: 62644.342565
If we take 3430 away from 3840, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 15:
686 goes into 4100 5 times with a remainder of 670.
The number 5 becomes the next digit in our result. 
Result so far: 62644.3425655
Subtract 3430 from 4100 to get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

The final outcome is 62644.3425655, with a leftover of 6.7e-06.
