78437 divided by 84 
Let's see how many times 84 fits into 78437.

Advancing to step 1:
84 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 84

Let's proceed to step 2:
The number 84 fits into 78 0 times, leaving a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (4) of the dividend behind the 78 and repeat the process: 784 / 84

Moving on to step 3:
If we divide 784 by 84, we get 9 and a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 756 from 784 and we're left with 28.
Bring next digit (3) of the dividend behind the 28 and repeat the process: 283 / 84

Step 4:
84 goes into 283 3 times with a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 93.0
If we subtract 252 from 283, we get 31.
Grab the next digit (7) from the dividend, add it to 31, then carry on: 317 / 84

Advancing to step 5:
The number 84 fits into 317 3 times, leaving a remainder of 65.
Record the quotient 3 as the next digit in the result. 
Result so far: 933.0
Deduct 252 from 317 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 6:
650 divided by 84 is 7 with a remainder of 62.
Write down 7 as next digit of the result. 
Result so far: 933.7
If we take 588 away from 650, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 7:
When dividing 620 by 84, we get 7 with a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 933.77
Deduct 588 from 620 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 933.77 and a remainder of 0.032.
