We look at the division of 83998929 by 651 
We want to figure out the number of times 83998929 can be divided by 651.

Going ahead to step 1:
651 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 651

Going ahead to step 2:
651 goes into 83 0 times with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Fetch the next digit (9) from the dividend, attach it to 83 and continue: 839 / 651

On to step 3:
If we divide 839 by 651, we get 1 and a remainder of 188.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 651 from 839, we get 188.
Take the next digit (9) from the dividend and append it to 188, then repeat: 1889 / 651

On to step 4:
651 can be fit into 1889 2 times, resulting in a remainder of 587.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 1302 away from 1889, we end up with 587.
Include the next digit (8) from the dividend after 587, then repeat: 5878 / 651

Let's proceed to step 5:
When dividing 5878 by 651, we get 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
The remainder is 19 after subtracting 5859 from 5878.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 651

On to step 6:
651 goes into 199 0 times with a remainder of 199.
Put 0 as the next digit of the answer. 
Result so far: 1290.0
Subtract 0 from 199 to get 199.
Append the next digit (2) from the dividend to 199 and continue with: 1992 / 651

Advancing to step 7:
The number 651 fits into 1992 3 times, leaving a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 12903.0
If we take 1953 away from 1992, we end up with 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 651

Step 8:
651 goes into 399 0 times with a remainder of 399.
Use 0 as the next digit of our solution. 
Result so far: 129030.0
If we take 0 away from 399, we end up with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Let's proceed to step 9:
651 can be fit into 3990 6 times, resulting in a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 129030.6
Subtract 3906 from 3990 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 10:
840 divided by 651 is 1 with a remainder of 189.
Use 1 as the next digit of our solution. 
Result so far: 129030.61
If we subtract 651 from 840, we get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Going ahead to step 11:
651 can be fit into 1890 2 times, resulting in a remainder of 588.
Write down 2 as next digit of the result. 
Result so far: 129030.612
Subtracting 1302 from 1890 leaves us with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Going ahead to step 12:
When dividing 5880 by 651, we get 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 129030.6129
If we subtract 5859 from 5880, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 13:
651 goes into 210 0 times with a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 129030.6129
Subtract 0 from 210 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 14:
When dividing 2100 by 651, we get 3 with a remainder of 147.
The number 3 becomes the next digit in our result. 
Result so far: 129030.612903
Deduct 1953 from 2100 and we're left with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Let's proceed to step 15:
When dividing 1470 by 651, we get 2 with a remainder of 168.
The number 2 becomes the next digit in our result. 
Result so far: 129030.6129032
If we take 1302 away from 1470, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 16:
651 can be fit into 1680 2 times, resulting in a remainder of 378.
Write down 2 as next digit of the result. 
Result so far: 129030.61290322
Deduct 1302 from 1680 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

The final outcome is 129030.61290322, with a leftover of 3.78e-07.
