98320385 divided by 646 
We want to divide 98320385 by 646.

Going ahead to step 1:
646 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 646

Going ahead to step 2:
If we divide 98 by 646, we get 0 and a remainder of 98.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 98, we end up with 98.
Bring next digit (3) of the dividend behind the 98 and repeat the process: 983 / 646

Going ahead to step 3:
The number 646 fits into 983 1 times, leaving a remainder of 337.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 646 away from 983, we end up with 337.
Append the next digit (2) from the dividend to 337 and continue with: 3372 / 646

Moving on to step 4:
When dividing 3372 by 646, we get 5 with a remainder of 142.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 3230 from 3372 and we're left with 142.
Grab the next digit (0) from the dividend, add it to 142, then carry on: 1420 / 646

On to step 5:
If we divide 1420 by 646, we get 2 and a remainder of 128.
Write down 2 as next digit of the result. 
Result so far: 152.0
Subtracting 1292 from 1420 leaves us with 128.
Grab the next digit (3) from the dividend, add it to 128, then carry on: 1283 / 646

Moving on to step 6:
646 can be fit into 1283 1 times, resulting in a remainder of 637.
Record the quotient 1 as the next digit in the result. 
Result so far: 1521.0
If we subtract 646 from 1283, we get 637.
Grab the next digit (8) from the dividend, add it to 637, then carry on: 6378 / 646

On to step 7:
646 can be fit into 6378 9 times, resulting in a remainder of 564.
Use 9 as the next digit of our solution. 
Result so far: 15219.0
If we take 5814 away from 6378, we end up with 564.
Append the next digit (5) from the dividend to 564 and continue with: 5645 / 646

On to step 8:
The number 646 fits into 5645 8 times, leaving a remainder of 477.
The next digit of our result is 8. 
Result so far: 152198.0
Deduct 5168 from 5645 and we're left with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

On to step 9:
When dividing 4770 by 646, we get 7 with a remainder of 248.
Write down 7 as next digit of the result. 
Result so far: 152198.7
If we subtract 4522 from 4770, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 10:
646 can be fit into 2480 3 times, resulting in a remainder of 542.
The next digit of our result is 3. 
Result so far: 152198.73
If we take 1938 away from 2480, we end up with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Let's proceed to step 11:
If we divide 5420 by 646, we get 8 and a remainder of 252.
Put 8 as the next digit of the answer. 
Result so far: 152198.738
Subtracting 5168 from 5420 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 12:
646 can be fit into 2520 3 times, resulting in a remainder of 582.
Use 3 as the next digit of our solution. 
Result so far: 152198.7383
If we take 1938 away from 2520, we end up with 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Advancing to step 13:
The number 646 fits into 5820 9 times, leaving a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 152198.73839
Subtracting 5814 from 5820 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 14:
The number 646 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 152198.73839
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 15:
If we divide 600 by 646, we get 0 and a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 152198.73839
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

After the division, we end up with 152198.73839 and a remainder of 6e-06.
