We divide 76751971 by 210
Let's see how many times 210 fits into 76751971.

Moving on to step 1:
210 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 210

Let's proceed to step 2:
If we divide 76 by 210, we get 0 and a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Include the next digit (7) from the dividend after 76, then repeat: 767 / 210

Going ahead to step 3:
210 goes into 767 3 times with a remainder of 137.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 630 from 767 and we're left with 137.
Bring next digit (5) of the dividend behind the 137 and repeat the process: 1375 / 210

Step 4:
1375 divided by 210 is 6 with a remainder of 115.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Subtracting 1260 from 1375 leaves us with 115.
Take the next digit (1) from the dividend and append it to 115, then repeat: 1151 / 210

Going ahead to step 5:
210 goes into 1151 5 times with a remainder of 101.
Put 5 as the next digit of the answer. 
Result so far: 365.0
The remainder is 101 after subtracting 1050 from 1151.
Include the next digit (9) from the dividend after 101, then repeat: 1019 / 210

Advancing to step 6:
210 goes into 1019 4 times with a remainder of 179.
Record the quotient 4 as the next digit in the result. 
Result so far: 3654.0
The remainder is 179 after subtracting 840 from 1019.
Bring next digit (7) of the dividend behind the 179 and repeat the process: 1797 / 210

On to step 7:
210 can be fit into 1797 8 times, resulting in a remainder of 117.
The next digit of our result is 8. 
Result so far: 36548.0
The remainder is 117 after subtracting 1680 from 1797.
Grab the next digit (1) from the dividend, add it to 117, then carry on: 1171 / 210

Going ahead to step 8:
210 goes into 1171 5 times with a remainder of 121.
Put 5 as the next digit of the answer. 
Result so far: 365485.0
If we subtract 1050 from 1171, we get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Going ahead to step 9:
210 can be fit into 1210 5 times, resulting in a remainder of 160.
Record the quotient 5 as the next digit in the result. 
Result so far: 365485.5
The remainder is 160 after subtracting 1050 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 10:
If we divide 1600 by 210, we get 7 and a remainder of 130.
Put 7 as the next digit of the answer. 
Result so far: 365485.57
If we take 1470 away from 1600, we end up 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.

Advancing to step 11:
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: 365485.576
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.

Going ahead to step 12:
210 can be fit into 400 1 times, resulting in a remainder of 190.
Record the quotient 1 as the next digit in the result. 
Result so far: 365485.5761
Deduct 210 from 400 and we're left 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.

Step 13:
When dividing 1900 by 210, we get 9 with a remainder of 10.
The next digit of our result is 9. 
Result so far: 365485.57619
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.

Advancing to step 14:
If we divide 100 by 210, we get 0 and a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 365485.57619
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 15:
1000 divided by 210 is 4 with a remainder of 160.
Use 4 as the next digit of our solution. 
Result so far: 365485.5761904
Subtract 840 from 1000 to 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.

On to step 16:
1600 divided by 210 is 7 with a remainder of 130.
The next digit of our result is 7. 
Result so far: 365485.57619047
Deduct 1470 from 1600 and we're left 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.

The final result is 365485.57619047 with a remainder of 1.3e-07.
