351698 ÷ 78 
We're looking to find how many times 78 goes into 351698.

Moving on to step 1:
3 divided by 78 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 78

Let's proceed to step 2:
The number 78 fits into 35 0 times, leaving a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Grab the next digit (1) from the dividend, add it to 35, then carry on: 351 / 78

Let's proceed to step 3:
351 divided by 78 is 4 with a remainder of 39.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 312 from 351 leaves us with 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 78

Advancing to step 4:
If we divide 396 by 78, we get 5 and a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
If we subtract 390 from 396, we get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 78

Moving on to step 5:
69 divided by 78 is 0 with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 450.0
Subtract 0 from 69 to get 69.
Grab the next digit (8) from the dividend, add it to 69, then carry on: 698 / 78

On to step 6:
78 can be fit into 698 8 times, resulting in a remainder of 74.
The next digit of our result is 8. 
Result so far: 4508.0
If we subtract 624 from 698, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 7:
When dividing 740 by 78, we get 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 4508.9
Deduct 702 from 740 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
78 can be fit into 380 4 times, resulting in a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 4508.94
Deduct 312 from 380 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 9:
The number 78 fits into 680 8 times, leaving a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 4508.948
If we take 624 away from 680, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 10:
560 divided by 78 is 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 4508.9487
If we subtract 546 from 560, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
78 can be fit into 140 1 times, resulting in a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 4508.94871
If we subtract 78 from 140, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 12:
78 can be fit into 620 7 times, resulting in a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 4508.948717
If we take 546 away from 620, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 13:
When dividing 740 by 78, we get 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 4508.9487179
Deduct 702 from 740 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 14:
78 can be fit into 380 4 times, resulting in a remainder of 68.
The next digit of our result is 4. 
Result so far: 4508.94871794
The remainder is 68 after subtracting 312 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

After the division, we end up with 4508.94871794 and a remainder of 6.8e-08.
