We're dividing 99879170 by 462 
We want to divide 99879170 by 462.

Step 1:
The number 462 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 462

Step 2:
462 can be fit into 99 0 times, resulting in a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Append the next digit (8) from the dividend to 99 and continue with: 998 / 462

On to step 3:
When dividing 998 by 462, we get 2 with a remainder of 74.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 924 away from 998, we end up with 74.
Include the next digit (7) from the dividend after 74, then repeat: 747 / 462

Advancing to step 4:
747 divided by 462 is 1 with a remainder of 285.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtracting 462 from 747 leaves us with 285.
Bring next digit (9) of the dividend behind the 285 and repeat the process: 2859 / 462

Step 5:
462 can be fit into 2859 6 times, resulting in a remainder of 87.
Record the quotient 6 as the next digit in the result. 
Result so far: 216.0
Deduct 2772 from 2859 and we're left with 87.
Include the next digit (1) from the dividend after 87, then repeat: 871 / 462

Going ahead to step 6:
If we divide 871 by 462, we get 1 and a remainder of 409.
Write down 1 as next digit of the result. 
Result so far: 2161.0
Deduct 462 from 871 and we're left with 409.
Grab the next digit (7) from the dividend, add it to 409, then carry on: 4097 / 462

Going ahead to step 7:
When dividing 4097 by 462, we get 8 with a remainder of 401.
Write down 8 as next digit of the result. 
Result so far: 21618.0
Subtracting 3696 from 4097 leaves us with 401.
Fetch the next digit (0) from the dividend, attach it to 401 and continue: 4010 / 462

On to step 8:
462 goes into 4010 8 times with a remainder of 314.
The next digit of our result is 8. 
Result so far: 216188.0
Subtract 3696 from 4010 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

On to step 9:
462 goes into 3140 6 times with a remainder of 368.
The next digit of our result is 6. 
Result so far: 216188.6
Deduct 2772 from 3140 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 10:
If we divide 3680 by 462, we get 7 and a remainder of 446.
The next digit of our result is 7. 
Result so far: 216188.67
Subtracting 3234 from 3680 leaves us with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Moving on to step 11:
462 can be fit into 4460 9 times, resulting in a remainder of 302.
Put 9 as the next digit of the answer. 
Result so far: 216188.679
Deduct 4158 from 4460 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Moving on to step 12:
If we divide 3020 by 462, we get 6 and a remainder of 248.
The next digit of our result is 6. 
Result so far: 216188.6796
Subtracting 2772 from 3020 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 13:
The number 462 fits into 2480 5 times, leaving a remainder of 170.
Put 5 as the next digit of the answer. 
Result so far: 216188.67965
If we take 2310 away from 2480, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 14:
1700 divided by 462 is 3 with a remainder of 314.
Use 3 as the next digit of our solution. 
Result so far: 216188.679653
The remainder is 314 after subtracting 1386 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Advancing to step 15:
3140 divided by 462 is 6 with a remainder of 368.
Use 6 as the next digit of our solution. 
Result so far: 216188.6796536
Subtracting 2772 from 3140 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 16:
3680 divided by 462 is 7 with a remainder of 446.
The next digit of our result is 7. 
Result so far: 216188.67965367
If we take 3234 away from 3680, we end up with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

The final outcome is 216188.67965367, with a leftover of 4.46e-07.
