9985792 ÷ 210 
We want to divide 9985792 by 210.

Step 1:
The number 210 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 210

Going ahead to step 2:
99 divided by 210 is 0 with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Take the next digit (8) from the dividend and append it to 99, then repeat: 998 / 210

On to step 3:
210 can be fit into 998 4 times, resulting in a remainder of 158.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 840 from 998 to get 158.
Bring next digit (5) of the dividend behind the 158 and repeat the process: 1585 / 210

On to step 4:
210 can be fit into 1585 7 times, resulting in a remainder of 115.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we subtract 1470 from 1585, we get 115.
Take the next digit (7) from the dividend and append it to 115, then repeat: 1157 / 210

Step 5:
1157 divided by 210 is 5 with a remainder of 107.
Use 5 as the next digit of our solution. 
Result so far: 475.0
If we subtract 1050 from 1157, we get 107.
Append the next digit (9) from the dividend to 107 and continue with: 1079 / 210

Moving on to step 6:
If we divide 1079 by 210, we get 5 and a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 4755.0
Subtracting 1050 from 1079 leaves us with 29.
Take the next digit (2) from the dividend and append it to 29, then repeat: 292 / 210

Moving on to step 7:
When dividing 292 by 210, we get 1 with a remainder of 82.
Use 1 as the next digit of our solution. 
Result so far: 47551.0
If we take 210 away from 292, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 8:
If we divide 820 by 210, we get 3 and a remainder of 190.
Use 3 as the next digit of our solution. 
Result so far: 47551.3
If we subtract 630 from 820, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 9:
If we divide 1900 by 210, we get 9 and a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 47551.39
The remainder is 10 after subtracting 1890 from 1900.
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.
Record the quotient 0 as the next digit in the result. 
Result so far: 47551.39
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.

On to step 11:
The number 210 fits into 1000 4 times, leaving a remainder of 160.
Use 4 as the next digit of our solution. 
Result so far: 47551.3904
If we subtract 840 from 1000, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 12:
1600 divided by 210 is 7 with a remainder of 130.
Write down 7 as next digit of the result. 
Result so far: 47551.39047
If we subtract 1470 from 1600, we 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.

Advancing to step 13:
210 goes into 1300 6 times with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 47551.390476
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.

Step 14:
The number 210 fits into 400 1 times, leaving a remainder of 190.
The number 1 becomes the next digit in our result. 
Result so far: 47551.3904761
Subtract 210 from 400 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 15:
When dividing 1900 by 210, we get 9 with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 47551.39047619
Subtract 1890 from 1900 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 47551.39047619, with a leftover of 1e-08.
