20870584 ÷ 651 
We're looking to find how many times 651 goes into 20870584.

Advancing to step 1:
The number 651 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 651

On to step 2:
20 divided by 651 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 651

Going ahead to step 3:
651 goes into 208 0 times with a remainder of 208.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 208 after subtracting 0 from 208.
Fetch the next digit (7) from the dividend, attach it to 208 and continue: 2087 / 651

Advancing to step 4:
2087 divided by 651 is 3 with a remainder of 134.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 1953 away from 2087, we end up with 134.
Take the next digit (0) from the dividend and append it to 134, then repeat: 1340 / 651

Let's proceed to step 5:
1340 divided by 651 is 2 with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we take 1302 away from 1340, we end up with 38.
Fetch the next digit (5) from the dividend, attach it to 38 and continue: 385 / 651

Step 6:
When dividing 385 by 651, we get 0 with a remainder of 385.
Write down 0 as next digit of the result. 
Result so far: 320.0
The remainder is 385 after subtracting 0 from 385.
Grab the next digit (8) from the dividend, add it to 385, then carry on: 3858 / 651

Going ahead to step 7:
The number 651 fits into 3858 5 times, leaving a remainder of 603.
Record the quotient 5 as the next digit in the result. 
Result so far: 3205.0
The remainder is 603 after subtracting 3255 from 3858.
Append the next digit (4) from the dividend to 603 and continue with: 6034 / 651

Moving on to step 8:
651 can be fit into 6034 9 times, resulting in a remainder of 175.
Use 9 as the next digit of our solution. 
Result so far: 32059.0
If we subtract 5859 from 6034, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 9:
When dividing 1750 by 651, we get 2 with a remainder of 448.
Record the quotient 2 as the next digit in the result. 
Result so far: 32059.2
Deduct 1302 from 1750 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Let's proceed to step 10:
If we divide 4480 by 651, we get 6 and a remainder of 574.
The next digit of our result is 6. 
Result so far: 32059.26
Deduct 3906 from 4480 and we're left with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Advancing to step 11:
If we divide 5740 by 651, we get 8 and a remainder of 532.
Put 8 as the next digit of the answer. 
Result so far: 32059.268
Subtracting 5208 from 5740 leaves us with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Moving on to step 12:
651 can be fit into 5320 8 times, resulting in a remainder of 112.
The number 8 becomes the next digit in our result. 
Result so far: 32059.2688
Subtracting 5208 from 5320 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final result is 32059.2688 with a remainder of 0.00112.
