We divide 99837457 by 210
We want to divide 99837457 by 210.

Advancing to step 1:
9 divided by 210 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 210

Advancing to step 2:
The number 210 fits into 99 0 times, leaving a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Append the next digit (8) from the dividend to 99 and continue with: 998 / 210

Moving on to step 3:
210 can be fit into 998 4 times, resulting in a remainder of 158.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 840 from 998 and we're left with 158.
Grab the next digit (3) from the dividend, add it to 158, then carry on: 1583 / 210

Let's proceed to step 4:
210 can be fit into 1583 7 times, resulting in a remainder of 113.
The next digit of our result is 7. 
Result so far: 47.0
The remainder is 113 after subtracting 1470 from 1583.
Fetch the next digit (7) from the dividend, attach it to 113 and continue: 1137 / 210

Moving on to step 5:
210 goes into 1137 5 times with a remainder of 87.
Write down 5 as next digit of the result. 
Result so far: 475.0
Deduct 1050 from 1137 and we're left with 87.
Append the next digit (4) from the dividend to 87 and continue with: 874 / 210

Moving on to step 6:
When dividing 874 by 210, we get 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 4754.0
Subtracting 840 from 874 leaves us with 34.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 210

Moving on to step 7:
345 divided by 210 is 1 with a remainder of 135.
Use 1 as the next digit of our solution. 
Result so far: 47541.0
Deduct 210 from 345 and we're left with 135.
Fetch the next digit (7) from the dividend, attach it to 135 and continue: 1357 / 210

Moving on to step 8:
The number 210 fits into 1357 6 times, leaving a remainder of 97.
The number 6 becomes the next digit in our result. 
Result so far: 475416.0
Subtract 1260 from 1357 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 9:
210 can be fit into 970 4 times, resulting in a remainder of 130.
The number 4 becomes the next digit in our result. 
Result so far: 475416.4
Subtract 840 from 970 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 10:
210 can be fit into 1300 6 times, resulting in a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 475416.46
Subtracting 1260 from 1300 leaves us with 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 11:
If we divide 400 by 210, we get 1 and a remainder of 190.
Put 1 as the next digit of the answer. 
Result so far: 475416.461
Subtracting 210 from 400 leaves us 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.

Going ahead to step 12:
210 goes into 1900 9 times with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 475416.4619
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.

Going ahead to step 13:
The number 210 fits into 100 0 times, leaving a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 475416.4619
Deduct 0 from 100 and we're left 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.

On to step 14:
210 goes into 1000 4 times with a remainder of 160.
Record the quotient 4 as the next digit in the result. 
Result so far: 475416.461904
Subtracting 840 from 1000 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 15:
When dividing 1600 by 210, we get 7 with a remainder of 130.
The number 7 becomes the next digit in our result. 
Result so far: 475416.4619047
Subtracting 1470 from 1600 leaves us with 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 16:
If we divide 1300 by 210, we get 6 and a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 475416.46190476
Deduct 1260 from 1300 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 475416.46190476 with a remainder of 4e-08.
