61649710 ÷ 391 
Our goal is to divide 61649710 by 391.

Let's proceed to step 1:
When dividing 6 by 391, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 391

Moving on to step 2:
When dividing 61 by 391, we get 0 with a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Append the next digit (6) from the dividend to 61 and continue with: 616 / 391

Going ahead to step 3:
When dividing 616 by 391, we get 1 with a remainder of 225.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 391 from 616 leaves us with 225.
Take the next digit (4) from the dividend and append it to 225, then repeat: 2254 / 391

Advancing to step 4:
The number 391 fits into 2254 5 times, leaving a remainder of 299.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 1955 from 2254 leaves us with 299.
Take the next digit (9) from the dividend and append it to 299, then repeat: 2999 / 391

Advancing to step 5:
When dividing 2999 by 391, we get 7 with a remainder of 262.
Write down 7 as next digit of the result. 
Result so far: 157.0
If we subtract 2737 from 2999, we get 262.
Bring next digit (7) of the dividend behind the 262 and repeat the process: 2627 / 391

Advancing to step 6:
391 can be fit into 2627 6 times, resulting in a remainder of 281.
Write down 6 as next digit of the result. 
Result so far: 1576.0
If we take 2346 away from 2627, we end up with 281.
Take the next digit (1) from the dividend and append it to 281, then repeat: 2811 / 391

Moving on to step 7:
When dividing 2811 by 391, we get 7 with a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 15767.0
Subtracting 2737 from 2811 leaves us with 74.
Include the next digit (0) from the dividend after 74, then repeat: 740 / 391

Advancing to step 8:
If we divide 740 by 391, we get 1 and a remainder of 349.
Use 1 as the next digit of our solution. 
Result so far: 157671.0
Subtract 391 from 740 to get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

On to step 9:
The number 391 fits into 3490 8 times, leaving a remainder of 362.
Write down 8 as next digit of the result. 
Result so far: 157671.8
The remainder is 362 after subtracting 3128 from 3490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Step 10:
391 can be fit into 3620 9 times, resulting in a remainder of 101.
Use 9 as the next digit of our solution. 
Result so far: 157671.89
The remainder is 101 after subtracting 3519 from 3620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Step 11:
391 can be fit into 1010 2 times, resulting in a remainder of 228.
The number 2 becomes the next digit in our result. 
Result so far: 157671.892
Subtract 782 from 1010 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 12:
If we divide 2280 by 391, we get 5 and a remainder of 325.
Record the quotient 5 as the next digit in the result. 
Result so far: 157671.8925
If we take 1955 away from 2280, we end up with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 13:
3250 divided by 391 is 8 with a remainder of 122.
Use 8 as the next digit of our solution. 
Result so far: 157671.89258
If we subtract 3128 from 3250, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 14:
The number 391 fits into 1220 3 times, leaving a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 157671.892583
The remainder is 47 after subtracting 1173 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 15:
391 can be fit into 470 1 times, resulting in a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 157671.8925831
The remainder is 79 after subtracting 391 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 16:
790 divided by 391 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 157671.89258312
If we take 782 away from 790, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 157671.89258312, and the remainder is 8e-09.
