79215808 ÷ 651 
We want to figure out the number of times 79215808 can be divided by 651.

Going ahead to step 1:
The number 651 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 651

Moving on to step 2:
When dividing 79 by 651, we get 0 with a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Include the next digit (2) from the dividend after 79, then repeat: 792 / 651

Step 3:
When dividing 792 by 651, we get 1 with a remainder of 141.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 651 away from 792, we end up with 141.
Append the next digit (1) from the dividend to 141 and continue with: 1411 / 651

Advancing to step 4:
If we divide 1411 by 651, we get 2 and a remainder of 109.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 109 after subtracting 1302 from 1411.
Include the next digit (5) from the dividend after 109, then repeat: 1095 / 651

On to step 5:
If we divide 1095 by 651, we get 1 and a remainder of 444.
Use 1 as the next digit of our solution. 
Result so far: 121.0
Deduct 651 from 1095 and we're left with 444.
Take the next digit (8) from the dividend and append it to 444, then repeat: 4448 / 651

Let's proceed to step 6:
If we divide 4448 by 651, we get 6 and a remainder of 542.
Use 6 as the next digit of our solution. 
Result so far: 1216.0
If we take 3906 away from 4448, we end up with 542.
Bring next digit (0) of the dividend behind the 542 and repeat the process: 5420 / 651

Going ahead to step 7:
651 goes into 5420 8 times with a remainder of 212.
Write down 8 as next digit of the result. 
Result so far: 12168.0
If we take 5208 away from 5420, we end up with 212.
Take the next digit (8) from the dividend and append it to 212, then repeat: 2128 / 651

Let's proceed to step 8:
If we divide 2128 by 651, we get 3 and a remainder of 175.
The number 3 becomes the next digit in our result. 
Result so far: 121683.0
Deduct 1953 from 2128 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 9:
651 can be fit into 1750 2 times, resulting in a remainder of 448.
Record the quotient 2 as the next digit in the result. 
Result so far: 121683.2
Subtracting 1302 from 1750 leaves us 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:
651 goes into 4480 6 times with a remainder of 574.
The number 6 becomes the next digit in our result. 
Result so far: 121683.26
Subtract 3906 from 4480 to get 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:
5740 divided by 651 is 8 with a remainder of 532.
Use 8 as the next digit of our solution. 
Result so far: 121683.268
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.

Advancing to step 12:
When dividing 5320 by 651, we get 8 with a remainder of 112.
Write down 8 as next digit of the result. 
Result so far: 121683.2688
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.

Our division results in 121683.2688 with a remaining 0.00112.
