99960967 ÷ 210 
We're looking to find how many times 210 goes into 99960967.

Advancing to step 1:
210 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 210

On to step 2:
The number 210 fits into 99 0 times, leaving a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Grab the next digit (9) from the dividend, add it to 99, then carry on: 999 / 210

Going ahead to step 3:
210 can be fit into 999 4 times, resulting in a remainder of 159.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 840 away from 999, we end up with 159.
Bring next digit (6) of the dividend behind the 159 and repeat the process: 1596 / 210

Moving on to step 4:
When dividing 1596 by 210, we get 7 with a remainder of 126.
Write down 7 as next digit of the result. 
Result so far: 47.0
Deduct 1470 from 1596 and we're left with 126.
Take the next digit (0) from the dividend and append it to 126, then repeat: 1260 / 210

Let's proceed to step 5:
When dividing 1260 by 210, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 476.0
If we take 1260 away from 1260, we end up with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 210

Moving on to step 6:
9 divided by 210 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 4760.0
If we take 0 away from 9, we end up with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 210

Moving on to step 7:
210 goes into 96 0 times with a remainder of 96.
Put 0 as the next digit of the answer. 
Result so far: 47600.0
The remainder is 96 after subtracting 0 from 96.
Take the next digit (7) from the dividend and append it to 96, then repeat: 967 / 210

Advancing to step 8:
When dividing 967 by 210, we get 4 with a remainder of 127.
Use 4 as the next digit of our solution. 
Result so far: 476004.0
Deduct 840 from 967 and we're left with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Advancing to step 9:
1270 divided by 210 is 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 476004.6
If we take 1260 away from 1270, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
210 can be fit into 100 0 times, resulting in a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 476004.6
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
210 can be fit into 1000 4 times, resulting in a remainder of 160.
Use 4 as the next digit of our solution. 
Result so far: 476004.604
The remainder is 160 after subtracting 840 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 12:
When dividing 1600 by 210, we get 7 with a remainder of 130.
Write down 7 as next digit of the result. 
Result so far: 476004.6047
Subtract 1470 from 1600 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 13:
When dividing 1300 by 210, we get 6 with a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 476004.60476
If we subtract 1260 from 1300, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
The number 210 fits into 400 1 times, leaving a remainder of 190.
The next digit of our result is 1. 
Result so far: 476004.604761
If we take 210 away from 400, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 15:
When dividing 1900 by 210, we get 9 with a remainder of 10.
The next digit of our result is 9. 
Result so far: 476004.6047619
Subtracting 1890 from 1900 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 16:
If we divide 100 by 210, we get 0 and a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 476004.6047619
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 476004.6047619 with a remainder of 1e-07.
