56012126 ÷ 651 
Let's see how many times 651 fits into 56012126.

Step 1:
651 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 651

Advancing to step 2:
651 can be fit into 56 0 times, resulting in a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 56, we end up with 56.
Bring next digit (0) of the dividend behind the 56 and repeat the process: 560 / 651

On to step 3:
560 divided by 651 is 0 with a remainder of 560.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 560, we get 560.
Take the next digit (1) from the dividend and append it to 560, then repeat: 5601 / 651

Let's proceed to step 4:
651 goes into 5601 8 times with a remainder of 393.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 393 after subtracting 5208 from 5601.
Take the next digit (2) from the dividend and append it to 393, then repeat: 3932 / 651

Advancing to step 5:
If we divide 3932 by 651, we get 6 and a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 86.0
The remainder is 26 after subtracting 3906 from 3932.
Fetch the next digit (1) from the dividend, attach it to 26 and continue: 261 / 651

On to step 6:
261 divided by 651 is 0 with a remainder of 261.
Record the quotient 0 as the next digit in the result. 
Result so far: 860.0
Subtracting 0 from 261 leaves us with 261.
Bring next digit (2) of the dividend behind the 261 and repeat the process: 2612 / 651

Advancing to step 7:
2612 divided by 651 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 8604.0
Deduct 2604 from 2612 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 651

On to step 8:
651 goes into 86 0 times with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 86040.0
Subtracting 0 from 86 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 9:
651 can be fit into 860 1 times, resulting in a remainder of 209.
Put 1 as the next digit of the answer. 
Result so far: 86040.1
Subtract 651 from 860 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Moving on to step 10:
When dividing 2090 by 651, we get 3 with a remainder of 137.
The next digit of our result is 3. 
Result so far: 86040.13
Deduct 1953 from 2090 and we're left with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Moving on to step 11:
When dividing 1370 by 651, we get 2 with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 86040.132
Subtract 1302 from 1370 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 12:
680 divided by 651 is 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 86040.1321
Subtract 651 from 680 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 13:
If we divide 290 by 651, we get 0 and a remainder of 290.
The next digit of our result is 0. 
Result so far: 86040.1321
If we subtract 0 from 290, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 14:
2900 divided by 651 is 4 with a remainder of 296.
Put 4 as the next digit of the answer. 
Result so far: 86040.132104
Subtracting 2604 from 2900 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 15:
2960 divided by 651 is 4 with a remainder of 356.
Record the quotient 4 as the next digit in the result. 
Result so far: 86040.1321044
Subtract 2604 from 2960 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

After the division, we end up with 86040.1321044 and a remainder of 3.56e-06.
